[PATCH] fbcon: fix scrollback with logo issue immediately after boot

From: David Hollister <[email protected]>

After the system boots with the logo, if the first action is a scrollback, the
screen may become garbled.  This patch ensures that the softback_curr value is
updated along with softback_in following the scrollback.
