--------------------------------

[ Upstream commit 1eb4ef12 ]

As per the new udp tunnel framework, drivers which need to know the
details of a port entry (i.e. port type) when it gets deleted should
use the .set_port / .unset_port callbacks.

Implementing the current .udp_tunnel_sync callback would mean that the
deleted tunnel port entry would be all zeros.  This used to work on
older firmware because it would not check the input when deleting a
tunnel port.  With newer firmware, the delete will now fail and
subsequent tunnel port allocation will fail as a result.
