Helge Deller fd1896dccc Revert "vgacon: Add check for vc_origin address range in vgacon_scroll()"

commit e4fc307d8e upstream.

This reverts commit 864f9963ec.

The patch is wrong as it checks vc_origin against vc_screenbuf,
while in text mode it should compare against vga_vram_base.

As such it broke VGA text scrolling, which can be reproduced like this:
(1) boot a kernel that is configured to use text mode VGA-console
(2) type commands:  ls -l /usr/bin | less -S
(3) scroll up/down with cursor-down/up keys
