nfsd: populate sin6_scope_id on callback address with scopeid from rq_addr on SETCLIENTID call
When a SETCLIENTID call comes in, one of the args given is the svc_rqst.
This struct contains an rq_addr field which holds the address that sent
the call. If this is an IPv6 address, then we can use the sin6_scope_id
field in this address to populate the sin6_scope_id field in the
callback address.
AFAICT, the rq_addr.sin6_scope_id is non-zero if and only if the client
mounted the server's link-local address.
