After receiving an unsolicited ABTS (meaning rxid is 0xFFFF), the
driver used the oxid from the initiator to match against a local
xri which may have been allocated for the io. The xri would be the
rxid - it's an invalid check resulting in the command not being
matched or erroneously matched.
Change the lookup to use the oxid and the SID to match against
received IO's original values.
