libceph, rbd, ceph: move ceph_osdc_alloc_messages() calls
The current requirement is that ceph_osdc_alloc_messages() should be called after oid and oloc are known. In preparation for preallocating message data items, move ceph_osdc_alloc_messages() further down, so that it is called when OSD op codes are known. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
