When compiling with MSVC the error below is hit:
drivers\net\mlx5\mlx5_tx.h(1148): error C2065: 'rte_v128u32_t':
undeclared identifier
Turns out that with MSVC the data type rte_v128u32_t is not used, but
its size needs to be known. This patch defines a macro to store that
size and replaces instances of sizeof(rte_v128u32_t) with that macro.
