Beat Küng d0a7490222 dshot: update timer generation before DMA request
This reloads the timer configuration before triggering DMA. Without that,
in rare cases, there were 17 bits sent instead of 16.
The 1. bit (1. pulse) was always wrong (too much), the rest of the bits
were the correct DShot packet that was meant to be sent.
