scsi: hisi_sas: Assign NCQ tag for all NCQ commands
Currently the NCQ tag is only assigned for FPDMA READ and FPDMA WRITE commands, and for other NCQ commands (such as FPDMA SEND), their NCQ tags are set in the delivery command to 0. So for all the NCQ commands, we also need to assign normal NCQ tag for them, so drop the command type check in hisi_sas_get_ncq_tag() [drop hisi_sas_get_ncq_tag() altogether actually], and always use the ATA command NCQ tag when appropriate.
