[Firmware] Movements retry too many times

# FarmBot OS version
`8.0.2`

# Behavior
Movements are currently attempted `n^2 + n` times, where `n` is the number of retries selected by the user. FarmBot OS attempts a movement `n + 1` times, and every time FarmBot OS tries a movement, the firmware attempts the movement `n` times.

# Expected
The movement retry mechanism should only be implemented in (one of) the firmware or FarmBot OS.
