tests/kms_fbcon_fbt: Reduce execution time by not calling wait_until_enabled()

After unset all CRTCs is expected that FBC and PSR is disabled,
calling wait_until_enabled() will make it wait until timeout to it
return false and pass the test.

So instead lets implement is_disabled() hook, as the
kmstest_unset_all_crtcs() is a synchronous call, the features will
be already disabled after it, so no need to do any wait.
