Subject[PATCH] fbcon: fix obvious bug in fbcon logo rotation code
From: Jasper Spaans <jasper@vs19.net>

This code fixes a tiny problem with the recent fbcon rotation changes:
fb_prepare_logo doesn't check the return value of fb_find_logo and that
causes a crash for my while booting.

Obvious & working & tested fix is here.
