[PATCH 4.9 13/71] drm/amdgpu: Fix SDMA HQD destroy error on gfx_v7

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Amber Lin <Amber.Lin@xxxxxxx>

[ Upstream commit caaa4c8a6be2a275bd14f2369ee364978ff74704 ]

A wrong register bit was examinated for checking SDMA status so it reports
false failures. This typo only appears on gfx_v7. gfx_v8 checks the correct
bit.
