Recently we introduced a patch for fixing an MST issue, but it caused a
regression on Club 3D since we could not set a refresh rate higher than
60Hz. This commit fixes this issue by adding a proper check after
validating the stream.
Fixes: 1bd038dc60e3 ("drm/amd/display: add mst port output bw check")
