net/mlx5: fix overflow in mempool argument

[ upstream commit 2fec07e ]

The mlx5_mprq_alloc_mp function makes shifting to the numeric constant
1, for sending it as a parameter to rte_mempool_create function.

The rte_mempool_create function expects to get void pointer (uintptr_t,
might be 64-bit) and instead gets a 32-bit variable, because the
numeric constant size is a 32-bit.
In case the shift is greater than 32 the variable might lose its value
even though the function might get 64-bit argument.

Change the size of the numeric constant 1 to uintptr_t.
