Luiz Capitulino 32ef5d8db0 realtime: disable timer migration 
It was found during code review that the kernel always try to
migrate timers away from idle CPUs to busy CPUs. Real-time
CPUs running dpdk polling threads for example, are busy so
they are a great candidate to receive timers from idle CPUs
(see get_nohz_timer_target() in the kernel sources).

It is not clear how this problem can affect real-time
applications and KVM-RT. However, for real-time and
high-performance the best thing is for a timer to always
fire in the CPU where it was created.

Resolves: rhbz#1323283
