[vm] Fix incorrect socket/unix-domain-socket binding code for shared sockets

When creating a binding socket with `shared: true` there will be one
underlying [OSSocket] used. Any following bind on the same address with
`shared: true` will re-use that [OSSocket].

The code that was searching for existing sockets is correct, but the
code that increments the refcount, ... was incorrectly using the start
of the linked list instead of the found existing socket instance.

Fixes https://github.com/dart-lang/sdk/issues/46634
