libceph: rename read_sparse_msg_*() to read_partial_sparse_msg_*()

These functions are supposed to behave like other read_partial_*()
handlers: the contract with messenger v1 is that the handler bails if
the area of the message it's responsible for is already processed.
This comes up when handling short reads from the socket.
