drm/amd/display: pass the right num of modes added

Browse source

[why]
In case if edid is null or corrupted we need to manually add
a single failsafe mode (640x480). If zero modes returned
DRM adds a different failsafe mode that is not accepted by
DP 1.2 compliance test

[how]
Return the number of modes manually added
