Kristof Provost a0c64a443e pf: ensure states passed to pf_free_state() are always unlinked
In pf_create_state() we can end up deleting the state immediately. This
can happen if we fail to map the relevant addresses or fail
normalization or fail to insert it into the state table.
If that happens we delete the state again with pf_free_state(). However,
this asserts that the state must be unlinked.

It's correct to simply set the state to PFTM_UNLINKED because we've not
yet linked it.
