drm/amd/display: Fix build breakage with CONFIG_DEBUG_FS=n

After commit 8799c0be ("drm/amd/display: Fix vblank refcount in vrr
transition"), a build with CONFIG_DEBUG_FS=n is broken due to a
misplaced brace, along the lines of:

  In file included from drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_trace.h:39,
                   from drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:41:

   8317 |         for_each_new_crtc_in_state(state, crtc, new_crtc_state, j)
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~

Move the brace within the #ifdef so that the file can be built with or
without CONFIG_DEBUG_FS.
