Log Message:
Kick fragments that would introduce several !MFFs in a reassembly chain.
The problem arises if we receive three fragments of the kind
3. A -> has MFF
1. B -> doesn't have MFF
2. C -> doesn't have MFF
Because of the received order B->C->A, we don't see that B is !MFF, and
therefore that there is a problem in this chain.
Now we do two checks, and drop us if:
* there is a fragment preceding us, and this fragment is !MFF, or
* there is a fragment following us, and we are !MFF
