ceph: set osd request message front length correctly
We didn't set the front length correctly. When messages used the message pool we ended up with the conservative max (4 KB), and the rest of the time the slightly less conservative estimate. Even though the OSD ignores the extra data, set it to the right value to avoid sending extra data over the network.
