net/mlx5: fix memory event on secondary process

Browse Source 
As the memory event is propagated to secondary processes, the event is
processed redundantly. This should be processed once because the data
structure used for MR and the event is global across the processes.

Fixes: 974f1e7ef146 ("net/mlx5: add new memory region support")
