This reverts commit edc064b4c589ab1bb69352523481bd6d997aa1ca.
In setups with multiple localnet ports w/o vlans (or multiple localnet
ports with the same vlans), that patch was trying to create the same
flows with action conjunction multiple times, which caused the following
assert:
0 0x00007ffff77cd834 in __pthread_kill_implementation () from /lib64/libc.so.6
1 0x00007ffff777b8ee in raise () from /lib64/libc.so.6

7 0x000000000045015c in main (argc=1, argv=0x7fffffffe218) at
controller/ovn-controller.c:5788
Reverting that patch means that flows such as
table_id=0, priority=180, vlan_tci=0x0000/0x1000, actions=conjunction(100,2/2)
remains after the localnet port is deleted.
Fixes: edc064b4c589 ("controller: Properly handle localnet flows in I+P.")

v2: Update test based on Dumitru's feedback i.e. check some localnet flows.
