set_desired_velocity_xy() to make clear only lat and lon axis are
updated.

We use the accel_rp_max, accel_y_max to check whether to apply accel
limiting or not.  This is related to separate from the
body-frame-feed-forward.

lthall 1bdde31f6b Copter: Fix zero throttle flip issue Stabilize
The problem is that the init_targets is intended to ensure the
controller doesn't build up the I term when the throttle is low. Because
it is poorly named (or used) it have been written to do something else.
Here I change it to do what the code is trying to use it to do.
