net/mlx5e: Use read lock for eswitch get callbacks

Browse Source 
In commit 367dfa1212 ("net/mlx5: Remove devl_unlock from
mlx5_eswtich_mode_callback_enter") all functions were converted
to use write lock without relation to their actual purpose.

Change the devlink eswitch getters to use read and not write locks.
