A complete duplication of binding should be allowed if on both new and
duplicated sockets a multicast address is bound and either
SO_REUSEPORT or SO_REUSEADDR is set.
But actually it works for the following combinations:
* SO_REUSEPORT is set for the fist socket and SO_REUSEPORT for the new;
* SO_REUSEADDR is set for the fist socket and SO_REUSEADDR for the new;
* SO_REUSEPORT is set for the fist socket and SO_REUSEADDR for the new;
and fails for this:
* SO_REUSEADDR is set for the fist socket and SO_REUSEPORT for the new.
Fix the last case.
