Miss rule creation is always done with ignore flow level bit set.
Older firmwares do not support that. Check FW support before setting the
ignore flow level bit.

The issue doesn't exist upstream, it was already fixed by a refactoring
commit ae430332557a ("net/mlx5: Refactor multi chains and prios support")
which was merged on v5.10.

Fixes: 278d51f24330 ("net/mlx5: E-Switch, Increase number of chains and priorities")
