net/9p: distinguish zero-copy requests
Add boolean `zc` member to struct p9_fcall to distinguish zero-copy
messages (not using the linear `sdata` buffer for message payload) from
regular messages (which do copy message payload to `sdata` before being
further processed).
This new member is appended to end of structure to avoid inserting huge
padding in generated layout.
