lxczfs: small fixes

- We expect destroy to fail in zfs_clone() so try to silence it so users are
  not irritated when they create zfs snapshots.
- Add -r recursive to zfs_destroy(). This code is only hit when a) the
  container has no snapshots or b) the user calls destroy with snapshots. So
  this should be safe. Without -r snapshots will remain.

7 years agoc/r: write status only after trying to parse the pid

c/r: write status only after trying to parse the pid

Previously, we write a "success" status but tried to parse the pid. This
meant that we wouldn't notice a successful restore but failure to parse the
pid, which was a little strange.

We still don't know the child pid, so we will end up with a restored
process tree and a running container, but at least in this case the API
will return false indicating that something failed.

We could kill(-1, 9) in this case, but since liblxc runs as root sometimes
(e.g. LXD), that would be a Very Bad Thing.

only valid number in there was the init process).
