drm/amd/display/dc/core/dc_link_dp: Mark 'result_write_min_hblank' as __maybe_unused

Browse Source 
It looks like it could be used inside the DC_TRACE_LEVEL_MESSAGE() macro.

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c: In function ‘dpcd_set_source_specific_data’:
 drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:4403:18: warning: variable ‘result_write_min_hblank’ set but not used [-Wunused-but-set-variable]
