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.
