Maru Newby fc91e158f2 Fix OVSBridge.get_port_ofport to handle empty output
Previously ovs_lib.OVSBridge.get_port_ofport() was not handling the
case where db_get_val() was returning None when no output was recieved
from ovs-vsctl.  This patch ensures that the TypeError that results
from this condition is appropriately handled.
