bridge: Clear out all Interface fields when an interface cannot be created.
		
When an Interface record is invalid (for example, when the interface that
it specifies does not exist and cannot be created), ovs-vswitchd would
leave any pre-existing data in its columns, except that it would set the
ofport column to -1 to indicate the error.  This was sometimes confusing
because, for example, the lacp_current field could still be set to "true"
if LACP has previously been active and up-to-date.

This commit changes ovs-vswitchd to reset all such data to its default
values when an interface is invalid.
