[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.
