net/mlx5: Fix offloading with ESWITCH_IPV4_TTL_MODIFY_ENABLE 



Only prio 1 is supported for nic mode when there is no ignore flow level
support in firmware. But for switchdev mode, which supports fixed number
of statically pre-allocated prios, this restriction is not relevant so
it can be relaxed.

Fixes: d671e109 ("net/mlx5: Fix tc max supported prio for nic mode")
