Subject: [PATCH] regex/mlx5: fix size of setup constants
The constant representing the size of the metadata is defined as an
unsigned int variable with 32-bit.
Similarly the constant representing the maximal output is also defined
as an unsigned int variable with 32-bit.
There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that
expects an expression of type size_t that might be 64-bit.
Change the size of the above constants to size_t.
