[ Upstream commit 4067662388f97d0f360e568820d9d5bac6a3c9fa ]
Just move error info related functions in super.c close to ext4_handle_error(). We'll want to combine save_error_info() with ext4_handle_error() and this makes change more obvious and saves a forward declaration as well. No functional change.
