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 (64 bits, unsigned) 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 will lose its value
even though the function can get 64-bit argument.
Change the size of the numeric constant 1 to 64-bit.
