bonding: fix crash when stopping inactive slave

When stopping the bond device we don't need to try and free up the LACPDU's
from deactivated devices since this is covered by
bond_mode_8023ad_deactivate_slave().

This fixes the following:
[    0.100569] PANIC in bond_ethdev_stop():
[    0.100589] line 1172        assert "port->rx_ring != NULL" failed
