libosd: Use of new blk_make_request
Use new blk_make_request() to allocate a request from bio
and avoid using deprecated blk_rq_append_bio().
This patch is dependent on a block layer patch titled:
[BLOCK] New blk_make_request() takes bio returns request
This is the last usage of blk_rq_append_bio in osd, it can now
be un-exported.
