ionic: bypass firmware cmds when stuck in reset
If the driver or firmware is stuck in reset state, don't bother
trying to use adminq commands. This speeds up shutdown and
prevents unnecessary timeouts and error messages.
This includes a bit of rework on ionic_adminq_post_wait()
and ionic_adminq_post_wait_nomsg() to both use
__ionic_adminq_post_wait() which can do the checks needed in
both cases.
