ipv6: dccp: add missing bind_conflict to dccp_ipv6_mapped
[ Upstream commit 990ff4d84408fc55942ca6644f67e361737b3d8e ]
While fuzzing kernel with syzkaller, Andrey reported a nasty crash
in inet6_bind() caused by DCCP lacking a required method.
Fixes: ab1e0a13d7029 ("[SOCK] proto: Add hashinfo member to struct proto")
