From: Eliad Peller <[email protected]> If recovery happened after mvm entered d0i3 (e.g. due to sysassert when releasing the bus), the mvm->state wasn't cleared properly, causing the ongoing recovery to fail (due to iwl_mvm_ref_sync failure).
This in turn fails the ongoing recovery, and triggers a reprobe, which terminates any ongoing wifi activity.
