Refactoring of the Atari floppy driver when converting to blk-mq

have completed. This is crucial in order to relase the ST-DMA
lock, which protects against concurrent access to the ST-DMA
controller by other drivers (some DMA related, most just related
to device register access - broken beyond compare, I know).

Applied, thanks!
