net/mlx5: fix work queue array size

Browse Source 
Indirection table size must be in log to communicate with verbs when the
number of queue is not a power of two, the maximum indirection table
size is use, but not converted to log2.  This makes a memory corruption.

Fixes: 4c7a0f5ff8 ("net/mlx5: make indirection tables shareable")
