udp: Remove unnecessary test for unspecified addr_out

If the configured output address is unspecified, we don't set the bind
address to it when creating a new socket in udp_tap_handler().  That sounds
sensible, but what we're leaving the bind address as is, exactly, the
unspecified address, so this test makes no difference.  Remove it.
