[PATCH] drm/tests: hdmi: fix infoframes tests

[mpenttil]

From: Mika Penttilä <mpenttil@xxxxxxxxxx>

drm_atomic_commit() calls drm_atomic_check_only() internally. Calling
drm_atomic_check_only() explicitly before the commit leaves the state
marked as checked and triggers drm_WARN_ON(state->checked) when the
commit checks the state again.

Remove the redundant explicit checks.

Fixes: 7436a87db99d ("drm/tests: hdmi: check the infoframes behaviour")
