ata_sff_hsm_move() triggers BUG if it sees a host state machine state that it dind't expect. The risk for data corruption when the condition occurs is low as it's highly unlikely that it would lead to spurious completion of commands. The BUG occasionally triggered for subtle race conditions in the driver. Let's downgrade it to WARN so that it doesn't kill the machine unnecessarily. Signed-off-by:
