kernel: Remove k_thread_priority_set() restriction
Removes the ISR restriction from k_thread_priority_set(). Since the first commit, the routine k_thread_priority_set() has had a restriction preventing it from being called from within the context of an ISR. As there does not (any longer) appear to be a reason why the restriction exists, it is being removed. Signed-off-by: Peter Mitsis <peter.mitsis@intel.com>
