score: Fix a release/cancel job race condition
Split up the potential thread priority change in the scheduler
release/cancel job operation. Protect the rate monotonic period state
with a dedicated SMP lock. This avoids a race condition during
_Rate_monotonic_Timeout() while _Rate_monotonic_Cancel() is called on
another processor.
