perf c2c: Fix argument type for percent()

mainline inclusion
from mainline-v5.12-rc1
commit 111c1415
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV
CVE: NA

-------------------------------------------------

For percent() its arguments are defined as integers; this is not
consistent with its consumers which pass u32 arguments.

Thus this patch makes argument type as u32 for percent().
