dload: ensure callback is always initialized once
Frontends rely on an initialization call for setup between downloads. Checking for intialization after checking for a completed download can skip initialization in cases where files are small enough to be downloaded all at once (FS#56408). Relying on previous download size can result in multiple initializations if there are multiple non-transfer events prior to the download starting (fS#56468). Introduce a new cb_initialized variable to the payload struct and use it to ensure that the callback is initialized exactly once prior to any actual events. Fixes FS#56408, FS#56468 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
