[PATCH net-next V2 1/5] net/mlx5e: XSK, Increase size for chunk_size param

From: Dragos Tatulea <dtatulea@nvidia.com>

When 64K pages are used, chunk_size can take the 64K value
which doesn't fit in u16. This results in overflows that
are detected in mlx5e_mpwrq_log_wqe_sz().

Increase the type to u32 to fix this.
