132f98c2dc iwlagn: simplify the iwl_device_cmd layout
This simplifies both the transport layer and the upper layer.

Kill the union in the device command, which avoids the funny syntax
we had: cmd->cmd.payload.

247c61d625 iwlagn: remove the callback in host commands
Before this patch, the upper layer could register a callback for each
host command. This mechanism allowed the upper layer to have
different callbacks for the same command ID. In fact, it wasn't used
and the rx_handlers is enough: same callback for all the command with
a specific command ID.

The iwl_send_add_station needs the access the command that was sent
while handling the response (regardless if the command was sent in
SYNC or ASYNC mode). So now, all the handlers receive the host
command that was sent. This implies a change in the handler signature.

390808db4a iwlagn: split remain-on-channel
If we're associated and want to do P2P at the same
time, the scan for remain-on-channel is currently
limited to 80ms because of the way the device will
behave in that case. Instead of doing that, split
up the dwell times into little pieces. It will not
actually be a single big dwell time then, but will
be close enough. This improves robustness of P2P
in such scenarios.

    iwlagn: do not use interruptible waits

    Since the dawn of its time, iwlwifi has used
    interruptible waits to wait for synchronous
    commands and firmware loading.

    This leads to "interesting" bugs, because it
    can't actually handle the interruptions; for
    example when a command sending is interrupted
    it will assume the command completed fully,
    and then leave it pending, which leads to all
    kinds of trouble when the command finishes
    later.

    Since there's no easy way to gracefully deal
    with interruptions, fix the driver to not use
    interruptible waits.

    This at least fixes the error
    iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'

    I have seen in P2P testing, but it is likely
    that there are other errors caused by this.

2e2a41d6ca iwlegacy: fix command queue timeout
iwlegacy version of fix:

commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc
Author: Johannes Berg <johannes.berg@intel.com>

    iwlagn: fix command queue timeout

    If the command queue is constantly busy,
    which can happen in P2P, the hangcheck
    timer will frequently find a command in
    it and will eventually reset the device
    because nothing sets the timestamp for
    this queue when commands are processed.

    Fix this by setting the timestamp when
    a command completes.

iwlegacy does not support P2P, but this patch fix possible
unneeded hardware resets, hence is needed.
