scst/include/backport.h: Define the 128 Gbit FC speed for older kernels

Browse Source 
The imported QLA29xx speed reporting uses FC_PORTSPEED_128GBIT. Supply
its upstream value before v4.16, following the existing 64 Gbit
definition and retaining vendor definitions when present. The newer
QLogic driver is the only current consumer; the legacy driver and other
transports are unaffected.
