ide-scsi: add debug_log() macro
Add debug_log() macro and convert the driver to use it.
[ This makes debug messages to be always prefixed with "ide-scsi: "
and use KERN_INFO level. ]
While at it:
* Change "DMA complete" debug message to "DMA finished" to match
other ATAPI device drivers.
* Use __func__.

ide: remove action argument in ide_do_drive_cmd
ide_do_drive_cmd is called only with ide_preempt action argument. So
we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.
This patch also includes two minor cleanups: 1) ide_do_drive_cmd
always succeeds so we don't need the return value; 2) the callers use
blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.
