A little offtopic for this patch, but can some explain this whole
mess about bios in Xen blkfront?  We can happily do partial completions
at the request later.

Also since the blk-mq conversion the call to blk_end_request_all is
completely broken, so it doesn't look like this code path is exactly
well tested.
