wifi: ath10k: move recovery check logic into a new work

[ Upstream commit f35a07a4842a88801d9182b1a76d178bfa616978 ]

Currently, ath10k has a recovery check logic. It will wait for the
last recovery to finish by wait_for_completion_timeout();

But in SDIO scenarios, the recovery function may be invoked from
interrupt context, where long blocking waits are undesirable and can
lead to system instability.

Additionally, Linux’s ordered workqueue processes one task at a time.
If a previous recovery is still queued or executing, new triggers are
ignored. This prevents accurate tracking of consecutive failures and
delays transition to the WEDGED state.

To address this, move the recovery check logic into a different
workqueue.
