drm/amd/display: fix possible buffer overflow relating to secure display
It is possible that adev->dm.dc->caps.max_links is greater than
AMDGPU_MAX_CRTCS. So, to not potentially access unallocated memory use
adev->mode_info.num_crtc to do the bounds check instead of
adev->dm.dc->caps.max_links.
Fixes: 1b11ff764aef ("drm/amd/display: Implement multiple secure display")
Fixes: b8ff7e08bab9 ("drm/amd/display: Fix when disabling secure_display")
