ipv6: dccp: add missing bind_conflict to dccp_ipv6_mapped 

commit 990ff4d84408fc55942ca6644f67e361737b3d8e upstream.

While fuzzing kernel with syzkaller, Andrey reported a nasty crash
in inet6_bind() caused by DCCP lacking a required method.

Fixes: ab1e0a13d7 ("[SOCK] proto: Add hashinfo member to struct proto")
