Call DVR VMARP notify outside of transaction

The dvr vmarp table update notification was being called inside
of the delete_port transaction in ML2, which can cause a yield
and lead to the glorious mysql/eventlet deadlock.

This patch moves it outside the transaction and adjusts it to
use an existing port dictionary rather than re-looking it up since
the port is now gone from the DB by the time it is called.
