net: dsa: rename the host FDB and MDB methods to contain the "bridge" namespace

We are preparing to add API in port.c that adds FDB and MDB entries that
correspond to the port's standalone database. Rename the existing
methods to make it clear that the FDB and MDB entries offloaded come
from the bridge database.

Since the function names lengthen in dsa_slave_switchdev_event_work(),
we place "addr" and "vid" in temporary variables, to shorten those.
