pfsync_sendout() is usually called when softc has accumulated
enough data to send a packet, and now is being requested to
add data that would overflow a packet. Thus, swi scheduled
at the end of pfsync_sendout() is going to service not a single
packet, but a couple of them, and the second one is containg
only one piece of pfsync data. This leads to coupling of pfsync
pps: every odd packet is full-sized and every even is undersized.

To fix this, a flag is added to softc - PFSYNCF_PUSH, which
indicates, whether we swi handler needs to sqeeze data from the
softc prior to sending packets.

In all cases when we need to send data immidiately, this flags
is raised prioir to swi_sched(). But in case of usual sc_len
overflow, it isn't raised.
