px4iofirmware: fixed a bug with override handling

this fixes a race condition between the DMA completion handler
updating registers in px4io and the mixer used for handling the
override state. The register set code could set r_page_servos[]
between the time when pwm_limit_calc() is called and the servos are
actually output.
