[kernel] fix get top thread error if NUM_PRIORITIES < 32 #165

Closed circl0 closed 7 years ago

circl0 commented 7 years ago

if NUM_PRIORITIES < 32, result will be negative?

looks good. I dont think it's ever been compiled with <32 priorities, though it does make sense to do so on memory constrained devices. 8 will probably suffice in that case.
