[PATCH] drm/amd/amdgpu: Fix logic bug in fatal error handling

[Srinivasan Shanmugam]

CC      drivers/gpu/drm/amd/amdgpu/amdgpu_ras.o
drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:2567:28: error: bitwise or with non-zero value always evaluates to true [-Werror,-Wtautological-bitwise-compare]
              if (adev->ras_hw_enabled | AMDGPU_RAS_BLOCK__DF)
                  ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

Presumably the author intended to test if AMDGPU_RAS_BLOCK__DF
bit was set if ras is enabled, so that's what I'm changing the
code to. Hopefully to do the right thing.
