[SCSI] lpfc 8.3.22: FC Discovery fixes 

FC Discovery fixes
- In lpfc_sli4_bpl2sgl byte swapping the SGL in word2.
- In lpfc_sli4_iocb2wqe byteswap the data for CMD_GEN_REQUEST64_CR type WQE.
- In lpfc_sli4_seq_abort_acc do not set the oxid into the iocb's xritag field.
- In lpfc_sli4_seq_abort_acc check the return value of lpfc_sli_issue_iocb.
- Inprove messages in this area.
