glebius d989f8363f It may happen that pfsync holds the last reference on a state. In this
case keys had already been freed. If encountering such state, then
just release last reference.

Not sure this can happen as a runtime race, but can be reproduced by
the following scenario:

- enable pfsync
- disable pfsync
- wait some time
- enable pfsync
