When using bpf(4) in immediate mode, and using kevent(2) to receive
notification of packet arrival, the usermode application isn't notified
until a second packet arrives.
This is because KNOTE() calls filt_bpfread() before bd_slen has been
updated with the newly arrived packet length, so it looks like there
is no data there.
Moving the bpf_wakeup() call for immediate mode to after bd_slen is set
fixes it.
