[dpdk-stable] [PATCH] net/mlx5: fix packet length check assert in MPRQ

[Alexander Kozyrev]

The assert that checks if there is a enough room for the
whole packet minus headroom data is written incorrectly.
The check should be negated in order to work properly.

Fixes: bd0d593 ("net/mlx5: enable MPRQ multi-stride operations")
