block: convert to dequeueing model (easy ones)
plat-omap/mailbox, floppy, viocd, mspro_block, i2o_block and
mmc/card/queue are already pretty close to dequeueing model and can be
converted with simple changes. Convert them.
While at it,
* xen-blkfront: !fs check moved downwards to share dequeue call with
normal path.
* mspro_block: __blk_end_request(..., blk_rq_cur_byte()) converted to
__blk_end_request_cur()
* mmc/card/queue: loop of __blk_end_request() converted to
__blk_end_request_all()
[ Impact: dequeue in-flight request ]
