rcu-tasks: Restore use of timers for non-RT kernels
The use of hrtimers for RCU-tasks grace-period delays works well in
general, but can result in excessive grace-period delays for some
corner-case workloads. This commit therefore reverts to the use of
timers for non-RT kernels to mitigate those grace-period delays.
