Currently the delayed work managing advertising duration and timeout is
part of the advertising instance structure. This is not correct as only
a single instance can be advertised at any given time. To implement
round robin advertising a single delayed work structure is needed.
To fix this the delayed work structure is being moved to the hci_dev
structure. The instance specific variable is renamed to "remaining_time"
to make it clear that this is the remaining lifetime of the instance and
not the current advertising timeout.
