Summary0000120: Make scheduler UNschedule when appropriate
DescriptionMake scheduler UNschedule when no accurate time difference number is available. The scheduler relies on this number to make its calculations and, as such, if it's wrong, the scheduling is wrong too, which is pretty serious. This is only an issue for the first schedule each time, ie, at start, or post sync loss.

I might do this by setting a invalidData cut flag pair with sync loss, and clearing it again with resync such that if the scheduler runs with the invalid data, it won't calculate anything, and will deschedule everything. Then the next time it runs without the cut flags, it'll be guaranteed to have good valid data. There might be a cleaner way, but I just wanted to record this idea.

Looking at this tonight because I see high-RPM spikes on sync loss on the HOTEL. I believe this is caused by bad data being written down, then processed, then potentially used (not actually in my case, but...).

The block of code in init.c around line 466-490 should be moved to a function and changed to a loop. It should then be called from init.c and from the sync loss function, too.

Tested for many many hundreds of km on the hotel.
