net/mlx5: E-switch, Annotate termtbl_mutex mutex destroy
Annotate mutex destroy to keep it symmetric to init sequence.
It should be destroyed after its users (representor netdevices) are
destroyed in below flow.
esw_offloads_disable()
esw_offloads_unload_rep()
Hence, initialize the mutex before creating the representors which uses
it.
