port: add a bounded single-port L2 flush

Browse Source 
port_l2_forget() flushes the whole table and polls the flush engine
without a bound. A topology change only needs to age out the port that
changed, and the STP tick cannot afford an unbounded poll: add
port_l2_forget_port() with a single-port mask and the same bounded wait
the static-entry helper uses.
