Jiawei Wang 7797b0fe64 net/mlx5: fix meter action pool protection 
The ASO meter action with flows creation could be supported on
multiple threads. The meter pools were created to manage the meter
object resources, if there is no room in the current meter pool then
resize the meter pool to the new pool size and free the old one.

There's a race condition while one thread resizes the meter pool and
the old pool resource be freed, and another thread query the meter
object by index on the old pool, the return value is invalid.

This patch adds a read-write lock to protect the pool resource while
resizing and query.
