lib/igt_kms: commit only the primary plane which is prepared

kms_atomic's test-only sub-test prepares only one primary plane
but igt_plane_commit() tries to commit all the primary planes.

For drivers having only one primary plane per display still
work fine but when there is more than one primary plane, since
FB_ID is not assigned for the second one, the API
igt_primary_plane_commit_legacy() ends up calling the CRTC
disable path incorrectly and hence failing the test.

Since only one primary plane has been prepared, commit only
that one by matching the primary_plane handle with the plane
which has been passed.

changes in v2:
	- compare the primary_plane and current plane's handle
	  to determine whether the current plane is the primary
	  plane instead of comparing the index
