console: vga_hw_screen_dump_ptr: take Error argument

Browse source 
All devices that register a screen dump callback via
graphic_console_init() are updated.

The new argument is not used in this commit. Error handling will
be added to each device individually later.

This change is a preparation to convert the screendump command
to the QAPI.
