Fixed port and system failure in handling SLI4 FC port function reset (CR 126551)

Fixed port and system failure in handling SLI4 FC port function reset (CR 126551)

When performing function reset to LPe16000 port which is connected to a fabric
and has targets (LUNs) discovered in the zone, sometimes the reset can fail and
end up in the port being unresponsive or system crash or hang. Now, when
reposting the SCSI SGL list after function reset, set the logical XRI allocated
bit in the logical XRI bmask to account for the XRIs posted, so duplicated
XRI will not be allocated later for new SGLs. Also, reset the used xri counts,
and updated them properly during function reset.
