[PATCH] virtfs-proxy-helper: Fix a resource leak in main()

[Alex Chen]

Only one of the options -s and -f can be used. When -f is used,
the fd is created externally and does not need to be closed.
When -s is used, a new socket fd is created, and this socket fd
needs to be closed at the end of main().
