There is logic in L1 that prevents the vehicle from trying to achieve
an impossible loiter entry (e.g. due to wind). That check makes the
vehicle track the loiter center if the tangential velocity is in the wrong
direction while loitering. After the vehicle flies through the center, it can
then turn the other way around to join the loiter.
This check is though too sensitive if it purely checks for the wrong direction,
and it can end in delayed loiter entry for no reason.
This commit increases the threshold to 2m/s of tangential velocity
in the wrong direction to trigger the check.
