[SeaBIOS] [PATCH] display_uuid(): fix incomplete check after the loop

[Laszlo Ersek]

In the v2->v3 change of what would become commit 37676f83
http://www.seabios.org/pipermail/seabios/2012-December/005166.html, the
defense against an initial "addr > end" condition ("wraparound") was
erroneously loosened.
