libceph: fix a osd request memory leak
If an invalid layout is provided to ceph_osdc_new_request(), its
call to calc_layout() might return an error. At that point in the
function we've already allocated an osd request structure, so we
need to free it (drop a reference) in the event such an error
occurs.
The only other value calc_layout() will return is 0, so make that
explicit in the successful case.
This resolves:
