This reverts commit e38030f3ff02684eb9e25e983a03ad318a10a2ea.
MSI flat-out doesn't work right on cx2388x devices yet. There are now
multiple reports of cards that hard-lock systems when MSI is enabled,
including my own HVR-1250 when trying to use its built-in IR receiver.
Disable MSI and it works just fine. Similar for another user's HVR-1270.
Issues have also been reported with the HVR-1850 when MSI is enabled,
and the 1850 behavior sounds similar to an as-yet-undiagnosed issue I've
seen with an 1800.

When commands time out, corruption ensues. As lbs_complete_command()
is called without locking, the command node is mistakenly freed twice.
Also fixed up locking here in a few other places.
The nature of command timeout may be that the card didn't even
acknowledge receipt of the request. Detect this case and reset dnld_sent
so that other commands don't hang forever.
When cmdnodes are moved between the free list and the pending list,
their list heads should be reinitialized. Fixed this.
Sometimes commands are completed without actually submitting them or
removing them from cmdpendingq. We must remember to remove them from
cmdpendingq in these cases, so handle this in lbs_complete_command().
Harmless signals generated during suspend/resume were interrupting
lbs_cmd. Convert to an uninterruptible sleep to avoid this.
lbs_thread must be woken up every time there is some new work to do.
I found that when 2 commands are queued, ther completion of the first
command would not wake up lbs_thread to submit the second. Poke lbs_thread
at the end of lbs_complete_command() to fix this.

WiFi throughput drops drastically when BT is turned on, BT and WiFi
are simultaneously transmitting/receiving traffic. This is particularly true
when BT has higher priority over WiFi, and hence the device defers TX frames.
The AP assumes that the channel is bad and reduces the data rate, implying
longer airtime, which exacerbates the problem further, resulting ultimately
in what is popularly called the "death-spiral" phenomenon. The use of PS-poll
in such scenarios guarantees a low but consistent throughput.
Since the death-spiral phenomenon is observed only when the RSSI is low, use
PS-poll only when RSSI is low and disable when high, with a known hysterisis.
This feature specifies the high and low thresholds and implements the
callbacks registered with mac80211, which will be called when threshold events
occur.

Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different.
