sched/isolation: Make CONFIG_CPU_ISOLATION depend on CONFIG_SMP 

[ Upstream commit 975776841e ]

kernel/sched/isolation.c obviously makes no sense without CONFIG_SMP, but
the Kconfig entry we have right now:

	config CPU_ISOLATION
		bool "CPU isolation"
		depends on SMP || COMPILE_TEST

allows the creation of pointless .config's which cause
build failures.
