[pgpool-committers: 2384] pgpool: Fix for [pgpool-general: 3377] Segmentation fault

Fix for [pgpool-general: 3377] Segmentation fault

The segmentation fault was occurring because of double freeing of the frontend
connection in child process error cleanup. Fixed by passing a double pointer to
frontend connection in backend_cleanup() function, so that assigning NULL to it
should become visible to caller.
