[dpdk-dev] [PATCH v2 2/4] compress/mlx5: fix constant size in QP creation

[Michael Baum]

The mlx5_compress_qp_setup function makes shifting to the numeric
constant 1, then sends it as a parameter to rte_calloc function.

The rte_calloc function expects to get size_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 bit and it 64-system, the variable
will lose its value even though the function can get 64-bit argument.

Change the size of the numeric constant 1 to size_t.
