cifs: fix srcip_matches() for ipv6

Browse Source 
srcip_matches() previously had code like this:

  srcip_matches(..., struct sockaddr *rhs) {
    /* ... */
    struct sockaddr_in6 *vaddr6 = (struct sockaddr_in6 *) &rhs;
    return ipv6_addr_equal(..., &vaddr6->sin6_addr);
  }

which interpreted the values on the stack after the 'rhs' pointer as an
ipv6 address.  The correct thing to do is to use 'rhs', not '&rhs'.
