scsi-disk: introduce dma_readv and dma_writev
These are replacements for blk_aio_readv and blk_aio_writev that allow customization of the data path. They reuse the DMA helpers' DMAIOFunc callback type, so that the same function can be used in either the QEMUSGList or the bounce-buffered case. This customization will be needed in the next patch to do zero-copy SG_IO on scsi-block. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
