I feel this is a bit too vague, how about either of these?
'9p: Rename req to rreq in trans_fd'
or
'9p/fd: Rename req to rreq'

We still have plenty of 'req' in client.c and all other transports, so
it would feel like a lie otherwise :)

Nitpick on title aside LGTM, I've picked this up for linux-next
