pg_restore: remove unnecessary code from restore_all_databases function

In commit 77152d26efefde2eed4, we added some functions and we missed to
remove some unnecessary lines. Those lines are not needed as we are using
memcpy to get the original copy before these lines.

Here, I am attaching a patch to fix this. Please review it.
