xenserver: In vif script, tolerate port existing when we (re)add it.
		
When a Windows VM boots, it initially has "vif" devices.  Then, when
XS Tools loads during boot, those "vif" devices disappear and then are
recreated under the same name.  The vif script is not called to remove
the old devices, but it is called to add the new ones.  It refused to do
this, however, because it saw the new device as having a duplicate name
(because the old was wasn't deleted).

This commit fixes the problem by making the vif script delete the port,
if it exists, before it adds it.

Bug #2425.

ovs-brcompatd: Delete Bridge record when deleting a bridge.
		
del_bridge() removed the reference to the Bridge record from the
Open_vSwitch table, but it didn't actually delete the Bridge record itself.
This fixes the problem.

Bug #2425.

ovs-brcompatd: Fix dangling reference in del_port().
		
Until now, del_port() was deleting Interface records without deleting the
Port record that referred to them.  OVSDB rejected that because it would
have caused a dangling reference from the Port to the Interfaces.  This
commit fixes the problem.

Bug #2425.
