Subject: team: Replace rcu_read_lock with a mutex in team_vlan_rx_kill_vid

From: Ido Schimmel <[email protected]>

[ Upstream commit 60a6531bfe49555581ccd65f66a350cc5693fcde ]

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.
