interface: Prevent bad inner-dot1q any exact-match configuration
Someone much more knowledgeable than I wrote:
For L3 IP forwarding, any VLAN tags on a packet must be exact
match to a sub-interface which means both outer and inner VLAN
tag IDs must be exact-matched to specific values defined of that
sub-interface. Without exact match on a L3 sub-interface, VPP
has no mechanism to know what VLAN tags to use for packet output,
such as ARP request packets or IP packets, on that sub-interface.
Thus, sub-interface with "inner-dot1q any" is not an exact match
sub-interface by definition since no match is present on inner
tag.
While in the area, fix a memory leak that would ensue on poorly
configured interfaces.
