Use sprint_sockip instead of sprint_sockaddr where appropriate

Also, in nfs_dupreq, use SOCK_NAME_MAX instead of 512 for size of buffer.
The DRC cache is per port, so sprint_sockaddr is still appropriate here.

Use gsh_client in state_nsm_client_t instead of sockaddr

In doing so, we also take a reference on the gsh_client while the nsm_client
exists so that it will be retained.
