[igt-dev] [PATCH i-g-t] lib/igt_kms: Don't reset VRR_ENABLED on every commit

[Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>]

If the VRR tests failed then there was a chance that VRR could be
left enabled when exiting the test so the VRR_ENABLED property was
reset to 0 whenever the pipe was reset.

However, in doing so the pipe's state was considered changed even
if VRR_ENABLED was already 0. This causes the pipe to be added to
commits where it previously wasn't.

Other tests with properties that can persist for failures (like color
management) don't bother resetting the properties - so this patch
changes VRR_ENABLED to work the same.

The VRR_ENABLED property was also never cleared after being set and
commit - leading to similar issues as the one described above. This
patch now clears it after being commit.
