[PATCH] percpu: fix a mismatch between code and comment

[Namhyung Kim]

When pcpu_build_alloc_info() searches best_upa value, it ignores current value
if the number of waste units exceeds 1/3 of the number of total cpus. But the
comment on the code says that it will ignore if wastage is over 25%.
Modify the comment.

 I used -U5 rather than 3 for you to see the mismatch at a glance. :-)
