[netdrvr wan] remove comx driver

the drivers have been broken since pre-2.4.0, like referencing a symbol
that was made procfs-internal in 2.3.x, haven't received maintainer
updates for about the same period and MOD_{INC,DEC}_USE_COUNT usage that
pretty much unfixable (inside warts of _horrible_ procfs abuse).
