SCSI device scan code was executing TEST UNIT READY command without explicitly setting dma direction in struct scsi_cmd to NONE, so command was passed to driver with dma direction set to DMA_FROM_DEVICE, inherited from older usage.

With WDC SDINDDH6-64G ufs device, that caused TEST UNIT READY to return error.

Fix that, by explicitly setting dma direction to NONE for TEST UNIT READY, and restoring it back DMA_FROM_DEVICE for the following READ CAPACITY.
