[SCSI] qla2xxx: Correct discrepancies during OVERRUN handling on FWI2-capable cards.
For recent ISPs, software must detect OVERRUN conditions by
checking the SS_RESIDUAL_OVER bit during CS_COMPLETE handling.
Update the driver to perform this check, which is consistent with
what earlier firmwares did by explicitly cracking open the
FCP_RSP statuses and returning an CS_DATA_OVERRUN.
