ide: add helpers for preparing sense requests
This is in preparation of removing the queueing of a sense request out
of the IRQ handler path.
Use struct request_sense as a general sense buffer for all ATAPI
devices ide-{floppy,tape,cd}.
tj: * blk_get_request(__GFP_WAIT) can't be called from do_request() as
it can cause deadlock. Converted to use inline struct request
and blk_rq_init().
* Added xfer / cdb len selection depending on device type.
* All sense prep logics folded into ide_prep_sense() which never
fails.
* hwif->rq clearing and sense_rq used handling moved into
ide_queue_sense_rq().
* blk_rq_map_kern() conversion is moved to later patch.
