Override has_pilot_input_for_override_clear() to use steering (rcmap
roll) and throttle, plus lateral on omni rovers, instead of the
Copter-style roll/pitch/yaw/throttle set.
This removes the need for the pointer to the first mode, and removes the
undefined behavior resulting from indexing past that first mode and
hoping the others follow (though this is unlikely to pose a problem in
practice).
Saves a few bytes of RAM and flash as the pointer is no longer needed
and code is no longer necessary to set it up.
Also fixes the bounds check condition of that array to match its size so
there is no longer the possibility of indexing one past it.
