ionic: bypass firmware cmds when stuck in reset
[ Upstream commit ca5fdf9a7c5b65968c718f2be159cda4c13556a1 ]
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.
