xfrm: interface: use IS_REACHABLE to avoid some compile errors
kernel test robot reported some compile errors:
ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_fini':
net/xfrm/xfrm_interface.c:900: undefined reference to `xfrm4_tunnel_deregister'
ia64-linux-ld: net/xfrm/xfrm_interface.c:901: undefined reference to `xfrm4_tunnel_deregister'
ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_init':
net/xfrm/xfrm_interface.c:873: undefined reference to `xfrm4_tunnel_register'
ia64-linux-ld: net/xfrm/xfrm_interface.c:876: undefined reference to `xfrm4_tunnel_register'
ia64-linux-ld: net/xfrm/xfrm_interface.c:885: undefined reference to `xfrm4_tunnel_deregister'
This happened when set CONFIG_XFRM_INTERFACE=y and CONFIG_INET_TUNNEL=m.
We don't really want xfrm_interface to depend inet_tunnel completely,
but only to disable the tunnel code when inet_tunnel is not seen.
So instead of adding "select INET_TUNNEL" for XFRM_INTERFACE, this patch
is only to change to IS_REACHABLE to avoid these compile error.
