Only check on launcher proc state when param visible is true.

When launcher moves away from TOP, param visible is false, should skip
the proc state check and move ahead to update AppOps.

Bug: 151835293
Test: Manual test, open another app and move launcher away from top
screen, observe AppOps is updated.
