drm/amd/powerplay: fix a signedness bugs 

Smatch complains about a signedness bug here:

        vega10_hwmgr.c:4202 vega10_force_clock_level()
        warn: always true condition '(i >= 0) => (0-u32max >= 0)'

Fixes: 7b52db39a4 ("drm/amd/powerplay: fix bug sclk/mclk
                     level can't be set on vega10.")
