Subject: display_uuid(): fix incomplete check after the loop
X-Git-Tag: rel-1.7.2~4

display_uuid(): fix incomplete check after the loop

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.
