arm/arm64: KVM: Don't clear the VCPU_POWER_OFF flag
commit 03f1d4c17edb31b41b14ca3a749ae38d2dd6639d upstream.
If a VCPU was originally started with power off (typically to be brought
up by PSCI in SMP configurations), there is no need to clear the
POWER_OFF flag in the kernel, as this flag is only tested during the
init ioctl itself.
