netdev-vport: Fix poll_add() implementation.

The existing implementation never worked because it used different strings
for notifier shash addition and lookup: for adding to the shash, it used
the vport name; for lookup, it used "<type>:<name>".  This fixes the
problem, by using "<type>:<name>" in both cases.
