drm/amd/display: Add error check for avi and vendor infoframe setup function

Browse Source 
The function fill_stream_properties_from_drm_display_mode() calls the
function drm_hdmi_avi_infoframe_from_display_mode() and the
function drm_hdmi_vendor_infoframe_from_display_mode(), but does
not check its return value. Log the error messages to prevent silent
failure if either function fails.
