[CRIU] [PATCH] unix: Fix double restoring of peerless unix sockets, which are peers for others

[Kirill Tkhai]

Since commit ea747b075508faa5780553969d87fb21fa3c487a receive queue for
such DGRAM sockets restores twice: in open_unix_sk() and post_open_unix_sk().
It should be made only once. So, keep that commit logic only for sockets
without alive sender.
