Fix comment for vcpu ioctl version of KVM_ENABLE_CAP.
KVM provides ioctl KVM_ENABLE_CAP to allow userspace to enable an
extension which is not enabled by default. For vcpu ioctl version,
it is available with the capability KVM_CAP_ENABLE_CAP. For vm ioctl
version, it is available with the capability KVM_CAP_ENABLE_CAP_VM.

tools/include/uapi/linux/kvm.h also needs the change?
Sean suggested "never update KVM's uapi headers in tools/ in KVM's tree"
So I dropped the change to tools/include/uapi/linux/kvm.h
