libceph: use cursor resid for loop condition

Use the "resid" field of a cursor rather than finding when the
message data position has moved up to meet the data length to
determine when all data has been sent or received in
write_partial_message_data() and read_partial_msg_data().

This is cleanup of old code related to:
