Subject: [PATCH 6/8] bsg-lib: handle bidi requests without block layer help

We can just stash away the second request in struct bsg_job instead
of using the block layer req->next_rq field, allowing for the eventual
removal of the latter.

Regardless of the ongoing discussion with Benjamin - 
Tested the scsi pass-through (ufs-bsg) path - nothing is broken.
