pf: Count holes rather than fragments for reassembly

Authored by kp on Oct 28 2018, 6:29 AM.



Avoid traversing the list of fragment entris to check whether the
pf(4) reassembly is complete. Instead count the holes that are
created when inserting a fragment. If there are no holes left, the
fragments are continuous.
