[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.
