[PATCH] v9fs: fix fd_close
If a 9pfs server crashes, v9fs_fd_close() is called. Subsequently, in cleaning up by performing a umount() on the FS that was provided by this server v9fs_fd_close() is called again, and uses the old, freed valus of trans->priv. This patch ensures that trans->priv can be freed only once, otherwise this function bails early.
