Allow capital letters in disk_map() and isduid() since disklabel.c
also allows them as of this revision:
----------------------------
revision 1.166
date: 2010/06/30 23:44:06;  author: halex;  state: Exp;  lines: +3 -1
allow uppercase A-F in the uid input

ok krw@ jsing@
=============================================================================

Together with my swapctl diff, this fixes swapctl -A for duids with
capital letters.

ok?
