net/mlx5: Fix offloading with ESWITCH_IPV4_TTL_MODIFY_ENABLE

commit 39bab83b119faac4bf7f07173a42ed35be95147e upstream.

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.
