[patch] Disklabel message tweak

[Michael McConville]

This is another trivial patch, but I've always found the disklabel
message "No label changes" confusing. For example, if you print (p), add
a label (a), write (w), print to check your changes (p), and then quit
(q), it seems odd to be told "No label changes".
