Remove unneeded hasattr check for bond methods

Base class for all switches GenericSwitchDevice implements fallback
for individual port handling in plug_bond_to_network and
unplug_bond_from_network functions. Since all switches are subclasses
of GenericSwitchDevice they implement default implementation for those
functions, so we do not need hasattr check.
