drm/amdgpu: fix r initial values

Victor Zhao · alexdeucher · commit 4b12ee6f426e · 2021-04-29T00:02:40.000-04:00
Sriov gets suspend of IP block &lt;dce_virtual&gt; failed as return
value was not initialized.

v2: return 0 directly to align original code semantic before this
was broken out into a separate helper function instead of setting
initial values
