protocol: pass the size of the data in the WRITE on-wire FOP
Capturing GlusterFS traffic with tcpdump and displaying it in Wireshark shows that the size of all WRITEs are 0 bytes. It seems that the attribute is not used, and the size is calculated an other way. Even if the size attribute is not used (yet), it should be set correctly to prevent confusing while debugging network traffic with Wireshark or other tools. Note that the on-wire format is not being changed with this patch. The size is already part of the structure that is exchanged between the client and server.
