libata: fix ata_scmd_need_defer()
Fix ata_scmd_need_defer() such that...
* whether NCQ is used or not is exactly determined using the same
criteria as the issue path.
* defer-check is performed in all cases.
This fixes race condition where turning off NCQ on the fly causes
non-NCQ commands sneak into NCQ phase.
