[PATCH v3] net: mana: Remove redundant netdev_lock_ops_to_full() calls

[Saurabh Sengar]

NET_SHAPER is always selected for MANA driver. When NET_SHAPER is enabled,
netdev_lock_ops_to_full() reduces effectively to only an assert for lock,
which is always held in the path when NET_SHAPER is enabled.

Remove the redundant netdev_lock_ops_to_full() call.
