vxlan: fix possible use of uninitialized in vxlan_igmp_{join, leave}
Test robot noticed that we check the return of vxlan_igmp_join and leave
but inside them there was a path that it could be used initialized.
It's not really possible because those if() inside these igmp functions
would always match as we can't have sockets of other type in there, but
this way we keep the compiler happy.
Fixes: 56ef9c909b40 ("vxlan: Move socket initialization to within rtnl scope")
