MFC r285190:
Fix if_loop so bpfwrite() can use it regardless of the state of
bd_hdrcmplt. As if_loop does not use link-level headers, its behavior
when used by bpfwrite() should be the same regardless of the state of
bd_hdrcmplt. Without this change, libpcap (and other BPF users that
work like it) fail when writing to loopback interfaces.
