If CONFIG_MPTCP=y, CONFIG_MPTCP_IPV6=n, and CONFIG_IPV6=m:

   net/mptcp/protocol.o: In function `__mptcp_tcp_fallback':
   protocol.c:(.text+0x786): undefined reference to `inet6_stream_ops'

Fix this by checking for CONFIG_MPTCP_IPV6 instead of CONFIG_IPV6, like
is done in all other places in the mptcp code.

Fixes: 8ab183deb26a3b79 ("mptcp: cope with later TCP fallback")
