timers/core: Correct callback order during CPU hot plug
...
On the tear-down path, the dead CPU callback for the timers was
misplaced within the 'cpuhp_state' enumeration. There is a hidden
dependency between the timers and block multiqueue. The timers
callback must happen before the block multiqueue callback otherwise a
RCU stall occurs.
Move the timers callback to the proper place in the state machine.
