For ceph_sync_write()/ceph_osdc_readpages()/ceph_osdc_writepages(), the 
user process or kernel thread will
wait for the pending OSD requests to complete on the corresponding 
req->r_completion. But it seems they only are waked up in handle_reply() 
and provided the replies are correct. What about if the replies are 
invalid, as the situations of label 'bad_put' in this function intended 
to capture, the waiters gotta hang there?
