[Intel-gfx] [PATCH i-g-t] lib/igt_kms: Only print changed mode objects during atomic commit.

[Maarten Lankhorst]

When we only print mode objects that have changed properties, we
reduce a lot of the spam. Fortuantely we have a single bitfield
now that gets printed when something is changed. Use that to decrease
the amount of spam.
