Remove struct ifnet's unused if_switchport member

This is a switch(4) left-over.

Even though it is defined under _KERNEL, a few ports do define it and
include <net/if_var.h>, so this removal warrants a REVISION bump for all
potential ports consumers (once ports bulk machines run on a snapshot
containing this commit).

OK mvs
