core: use C accessors in core/save-xml.c instead of callback

We now can loop over devices from C and check for selection.
So let's get rid of the last user of the call_for_all_devices()
callback.

Code readability improvement is not stellar, but one less
place where we shoe-horn user data through a void-pointer.
