svc: Change the svc_sock in the rqstp structure to a transport

Browse Source 
The rqstp structure contains a pointer to the transport for the
RPC request. This functionaly trivial patch adds an unamed union
with pointers to both svc_sock and svc_xprt. Ultimately the
union will be removed and only the rq_xprt field will remain. This
allows incrementally extracting transport independent interfaces without
one gigundo patch.
