net: lan966x: fix a couple off by one bugs

Browse source

The lan966x->ports[] array has lan966x->num_phys_ports elements.  These
are assigned in lan966x_probe().  That means the > comparison should be
changed to >=.

The first off by one check is harmless but the second one could lead to
an out of bounds access and a crash.
