Subject: [PATCH] mainloop: Deinit the new config when reverting to the old one

Upstream-Status: Backport

When reloading, and the new config fails, deinit it before initializing
the old config. This is so that conflicting things do not remain held by
the half-initialized new config, while the old tries to take it
over. (It also removed a couple of memory leaks, most likely.)

The reason we can do this, is because cfg_tree_stop() (called by
cfg_deinit()) goes over all the known nodes, and log_pipe_deinit() is
also smart enough to not deinit a node that has not been inited before.
