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

drivers/gpu/drm/amd/display/dc/dce/dce_link_encoder.c: In function dce110_link_encoder_update_mst_stream_allocation_table:
drivers/gpu/drm/amd/display/dc/dce/dce_link_encoder.c:1229:11: warning: variable value0 set but not used [-Wunused-but-set-variable]

It is not used since commit 4562236b3bc0 ("drm/amd/dc:
Add dc display driver (v2)")
