net/mlx5: Fix tc max supported prio for nic mode

Only prio 1 is supported if firmware doesn't support ignore flow
level for nic mode. The offending commit removed the check wrongly.
Add it back.

Fixes: 0c77dce8c4d3 ("net/mlx5e: E-Switch, Offload all chain 0 priorities when modify header and forward action is not supported")
