net/mlx5e: Add a lock on tir list
[ Upstream commit 80a2a9026b24c6bd34b8d58256973e22270bedec ]
Refresh tirs is looping over a global list of tirs while netdevs are
adding and removing tirs from that list. That is why a lock is
required.
Fixes: 724b2aa15126 ("net/mlx5e: TIRs management refactoring")
