If this is supposed to match the previous behavior, shouldn't the condition be
"!= COMMIT_ATOMIC". Both flags are set from igt_pipe_commit() which is not
called in the atomic case. However, the flags aren't set to false in
igt_atomic_prepare_crtc_commit(). That actually sounds like a bug?

Can't plane->rotation_changed be set unconditionally here? The legacy primary
plane commit has an assert for rotation_changed == false and perhaps the cursor
version should have the same.
