vela: Protect against divide by zero
If the total cycle count is zero (for whatever reason), then a divide by
zero can occur when calculating the midpoint_fps.
This change protects against that by detecting when that is the case and
instead setting the midpoint_fps to nan.
Further calculations using that variable is safe and results in nan
throughout.
