HAL_ChibiOS: don't send dshot commands when safety is on

[tridge]

we shouldn't be sending anything till safety is off

Heads up @bugobliterator - the "ChibiOS" label was applied to this issue.

@tridge this stops the LEDs working until the safety is pressed which rather defeats the purpose - so I don't think this is the right change. What are you trying to achieve?

ahh, I'd forgotten about the LEDs.
I've had a lot of problems with the ESCs (holybro 4-in-1 blheli32) not initialising properly on boot. I thought this helped, but its intermittent, so hard to track down

If there is a problem we should try and fix it since many boards do not have safety switches. So what issue do you see? dshot initializes quite late - I have never seen an issue with the LEDs on my TMotor 4-in-1
