History
Lawrence Stewart 9a7e6bac47 Consumers of bpfdetach() expect it to remove all bpf_if structs from the 
bpf_iflist list which reference the specified ifnet. The existing implementation
only removes the first matching bpf_if found in the list, effectively leaking
list entries if an ifnet has been bpfattach()ed multiple times with different
DLTs.

Fix the leak by performing the detach logic in a loop, stopping when all bpf_if
structs referencing the specified ifnet have been detached and removed from the
bpf_iflist list.

Whilst here, also:

- Remove the unnecessary "bp->bif_ifp == NULL" check, as a bpf_if should never
  exist in the list with a NULL ifnet pointer.

- Except when INVARIANTS is in the kernel config, silently ignore the case where
  no bpf_if referencing the specified ifnet is found, as it is harmless and does
  not require user attention.
