Huacai Chen 4e8b49b325 ata: libata: Improve return value of atapi_check_dma()
atapi_check_dma() allows a LLD to filter ATAPI commands, returning a
status indicating whether or not it is OK to use DMA for the supplied
ATAPI command.

Change atapi_check_dma() to return -EOPNOTSUPP instead of 1 for an
ATAPI command that is not allowed to use DMA.
