Alex Richardson fa2528ac64 Use atomic loads/stores when updating td->td_state 
KCSAN complains about racy accesses in the locking code. Those races are
fine since they are inside a TD_SET_RUNNING() loop that expects the value
to be changed by another CPU.

Use relaxed atomic stores/loads to indicate that this variable can be
written/read by multiple CPUs at the same time. This will also prevent
the compiler from doing unexpected re-ordering.

Reported by:	GENERIC-KCSAN
Test Plan:	KCSAN no longer complains, kernel still runs fine.
