Subject: [PATCH -next] drm/amdgpu: remove set but not used variable 'ring'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/amdgpu/psp_v10_0.c: In function 'psp_v10_0_ring_stop':
drivers/gpu/drm/amd/amdgpu/psp_v10_0.c:230:19: warning:
 variable 'ring' set but not used [-Wunused-but-set-variable]

It not used since commit
4ef72453311a ("drm/amdgpu: added api for stopping psp ring (v2)")
