libceph: consolidate message prep code
In prepare_write_message_data(), various fields are initialized in
preparation for writing message data out. Meanwhile, in
read_partial_message(), there is essentially the same block of code,
operating on message variables associated with an incoming message.
Generalize prepare_write_message_data() so it works for both
incoming and outcoming messages, and use it in both spots. The
did_page_crc is not used for input (so it's harmless to initialize
it).
