net: Keep ignoring isolated cpuset change
RPS cpumask can be overriden through sysfs/syctl. The boot defined
isolated CPUs are then excluded from that cpumask.
However HK_TYPE_DOMAIN will soon integrate cpuset isolated
CPUs updates and the RPS infrastructure needs more thoughts to be able
to propagate such changes and synchronize against them.
Keep handling only what was passed through "isolcpus=" for now.
