net/mlx5: work around gcc error

Browse Source 
RHEL 7.1's GCC for POWER8 reports the following error in one rte_memcpy()
macro call by mlx5:

 error: array subscript is above array bounds [-Werror=array-bounds]

It appears to be a GCC bug which can be worked around by making parentheses
more explicit.
