[PATCH xtables-addons 6/8] xt_condition: use `proc_net_condition` member of `struct condition_net`to signal that `condition_net_exit` has been called.

[Jeremy Sowden <jeremy@xxxxxxxxxx>]

There's no need for a separate boolean flag when we can just set
`proc_net_condition` to `NULL` after the directory has been removed.
