libceph: allocate ceph_osd with GFP_NOFAIL
create_osd() is called way too deep in the stack to be able to error out in a sane way; a failing create_osd() just messes everything up. The current req_notarget list solution is broken - the list is never traversed as it's not entirely clear when to do it, I guess. If we were to start traversing it at regular intervals and retrying each request, we wouldn't be far off from what __GFP_NOFAIL is doing, so allocate OSD sessions with __GFP_NOFAIL, at least until we come up with a better fix.
