cluster/ec: Fix race in timer cancellation
A race in timer cancellation for delayed unlock could cause a crash
if the cancelling thread fails to cancel the timer because it has
already been fired but not executed, and the callback is scheduled
out of the CPU, delaying it until the thread has released important
resources needed by the callback.
This patch improves the handling of this case to make it robust.
