[patch] block: remove bio walking

IDE driver was the only user of bio walking code.
was in -bk10 :-(

The MMC driver also uses this.  Please don't remove.
OK I'll just drop this patch but can't we also use scatterlists in MMC?

The point is that I now think bio walking was a mistake and accessing
bios directly from low-level drivers is a layering violation (thus
all the added complexity). Moreover with fixed IDE PIO and without
bio walking code it should be possible to shrink struct request by
removing all "current" entries.
I agree, it's much nicer and it allows to drop the cbio fields in struct
request which is good.
