drm/amd/display: Consult MCCS FreeSync cap only if requested & supported
When the do_mccs parameter is false, we don't call
dm_helpers_read_mccs_caps, so sink->mccs_caps.freesync_supported is
unlikely to be true.
Fixes: 6f71d5dd3206 ("drm/amd/display: Read sink freesync support via mccs")
Bug: https://gitlab.freedesktop.org/drm/amd/-/work_items/5286
