[dpdk-stable] [PATCH 6/7] regex/mlx5: improve constants type in QP buffers creation

The constant representing the size of the metadata is defined as a
regular number (32-bit signed), even though all of its uses request an
unsigned int variable.
Similarly the constant representing the maximal output is also defined
as a regular number, even though all of its uses request an unsigned int
variable.

Change the type of the above constants to unsigned.
