Log Message:
restore the fallback to non-NCQ on retries, do this after WDIORETRIES_SINGLE
retries, but only for non-FUA I/O; also only do the ATA_SINGLE fallback
when non-FUA
this makes sure that bio with ATA_SINGLE is not attempted as NCQ -
the ATA_SINGLE I/O is usually done using PIO by drivers which
actually support it, and thus are not compatible with DMA-only NCQ
