net/mlx5e: Fix interoperability between XSK and ICOSQ recovery flow
[ Upstream commit 17958d7 ] Both regular RQ and XSKRQ use the same ICOSQ for UMRs. When doing recovery for the ICOSQ, don't forget to deactivate XSKRQ. XSK can be opened and closed while channels are active, so a new mutex prevents the ICOSQ recovery from running at the same time. The ICOSQ recovery deactivates and reactivates XSKRQ, so any parallel change in XSK state would break consistency. As the regular RQ is running, it's not enough to just flush the recovery work, because it can be rescheduled.
