4.2.8-ckt3 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Ido Schimmel <redacted>

commit 60a6531bfe49555581ccd65f66a350cc5693fcde upstream.

We can't be within an RCU read-side critical section when deleting
VLANs, as underlying drivers might sleep during the hardware operation.
Therefore, replace the RCU critical section with a mutex. This is
consistent with team_vlan_rx_add_vid.
