  Fixed the assertion on the flags set in pkt->ol_flags for vectorized MPRQ.
With vectorized MPRQ the CQs are processed before copying the MPRQ bufs
so the valid assertion is that the expected flag is set and not that
the pkt->ol_flags equlas this flag alone.

Fixes: 0f20acbf5eda ("net/mlx5: implement vectorized MPRQ burst")
