msm: mdss: dsi: fix handling of ulps_suspend feature flag 



In the current implementation, when ulps_suspend feature is enabled, it
results in ULPS mode being configured even when turning off clocks
during idle screen use cases. Fix this by correcting the conditional
logic when turning off the link clocks.
