svcrdma: RDMA support not yet compatible with RPC6 



RPC6 requires that it be possible to create endpoints that listen
exclusively for IPv4 or IPv6 connection requests. This is not currently
supported by the RDMA API.

This fixes a server RDMA regression introduced by 37498292 "NFSD:
Create PF_INET6 listener in write_ports".
