drm/amdgpu/smu13: fix profile reporting

The following 3 commits landed in parallel:
commit d7d2688bf4ea ("drm/amd/pm: update workload mask after the setting")
commit 7a1613e47e65 ("drm/amdgpu/smu13: always apply the powersave optimization")
commit 7c210ca5a2d7 ("drm/amdgpu: handle default profile on on devices without fullscreen 3D")
While everything is set correctly, this caused the profile to be
reported incorrectly because both the powersave and fullscreen3d bits
were set in the mask and when the driver prints the profile, it looks
for the first bit set.
