Subject: drm/amdgpu: fix array out of bounds

From: tom will <os@iscas.ac.cn>

commit 484f689fc9d4eb91c68f53e97dc355b1b06c3edb upstream.

When the initial value of i is greater than zero,
it may cause endless loop, resulting in array out
of bounds, fix it.

This is a port of the radeon fix to amdgpu.
