Michael Baum a94e89e47b net/mlx5: fix race condition in counter pool resizing 
Counter management structure has array of counter pools. This array is
invalid in management structure initialization and grows on demand.

The resizing include:
1. Allocate memory for the new size.
2. Copy the existing data to the new memory.
3. Move the pointer to the new memory.
4. Free the old memory.

The third step can be performed before for this function, and compiler
may do that, but another thread might read the pointer before coping and
read invalid data or even crash.

This patch allocates memory for this array once in management structure
initialization and limit the counters number by 16M.
