[PATCH 2/4] virtiofsd: fv_create_listen_socket error path socket leak

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <dgilb...@redhat.com>

If we fail when bringing up the socket we can leak the listen_fd;
in practice the daemon will exit so it's not really a problem.

Fixes: Coverity CID 1413121
