ice: Handle critical FW error during admin queue initialization

Browse source

A race condition between FW and SW can occur between admin queue setup and
the first command sent. A link event may occur and FW attempts to notify a
non-existent queue. FW will set the critical error bit and disable the
queue. When this happens retry queue setup.
