The assert in dynamic flow metadata handling is wrong after the
fix for the performance degradation. The assert meant to check
the metadata mask but was updated with the metadata offset instead.
Fix this assert and restore proper metadata mask checking.

Fixes: 6c55b62 ("net/mlx5: set dynamic flow metadata in Rx queues")
