Fix regression plugging 802.3ad port group

Netmiko devices were sending no commands to the switch since
plug_bond_to_network is overridden in
networking_generic_switch/devices/netmiko_devices/__init__.py
and PLUG_BOND_TO_NETWORK to set to None.

Closes-Bug: #2041516
Change-Id: I27425c2fc0318688f730a4e84816bcfc7e901b51
(cherry picked from commit 40399f2)
