scsi: pm8001: Fix NCQ NON DATA command completion handling

[ Upstream commit 1d6736c3e162061dc811c76e605f35ef3234bffa ]

NCQ NON DATA is an NCQ command with the DMA_NONE DMA direction and so a
register-device-to-host-FIS response is expected for it.

However, for an IO_SUCCESS case, mpi_sata_completion() expects a
set-device-bits-FIS for any ata task with an use_ncq field true, which
includes NCQ NON DATA commands.

Fix this to correctly treat NCQ NON DATA commands as non-data by also
testing for the DMA_NONE DMA direction.
