sched: Remove invalid cases from cpuset_cpu_active

This fixes a merge error from when updating from 2.6.35 kernel.
The case cpu_down_prepare/frozen is not present in the
cpuset_cpu_active function in the kernel which the QUIC kernel
is based off of.  The inclusion of this case hurts cpu_hotplug
performance on a cpu_down operation.
