Ilya Dryomov bcbab1db6c rbd: introduce obj_req->osd_reqs list
Since the dawn of time it had been assumed that a single object request
spawns a single OSD request.  This is already impacting copyup: instead
of sending empty and current snapc copyups together, we wait for empty
snapc OSD request to complete in order to reassign obj_req->osd_req
with current snapc OSD request.  Looking further, updating potentially
hundreds of snapshot object maps serially is a non-starter.

Replace obj_req->osd_req pointer with obj_req->osd_reqs list.  Use
osd_req->r_private_item for linkage.
