net/mlx5: E-Switch, use state lock for vport state changes

Browse source 
Protect vport admin state modifications and vport iteration with the
eswitch state_lock mutex to ensure proper serialization of concurrent
vport state changes.

Currently, calls to mlx5_modify_vport_admin_state() and loops iterating
over eswitch vports can race with each other, potentially leading to
inconsistent vport state. Fix this by acquiring esw->state_lock
