Fix for FDISC failures after firmware reset or link bounce (CR 126779)

The driver failed to discover target on vports after a link bounce. This is a
regression on SLI4 adapters where the SID in the FDISC was set to a non-zero
value. There is no use case for a non-zero SID in the FDISC. Thefix is to clear
fc_myDID to guarentee a zero SID
