BUG/MINOR: haproxy: free init_env in deinit only if allocated

This fixes 7b78e1571 (" MINOR: mworker: restore initial env before wait
mode").

In cases, when haproxy starts without any configuration, for example:
'haproxy -vv', init_env array to backup env variables is never allocated. So,
we need to check in deinit(), when we free its memory, that init_env is not a
NULL ptr.
