KVM: arm64: Fix the KVM_ARM_PREFERRED_TARGET documentation

KVM_ARM_PREFERRED_TARGET has never set a feature bit: the original arm64
implementation zeroed the bitmap, and kvm_vcpu_preferred_target(), which
only ever zeroed it, was removed by commit 5346f7e13e5e ("KVM: arm64:
Always return generic v8 as the preferred target"). The ENODEV error had
gone earlier still, with commit 08e873cb70f3 ("KVM: arm64: Change the
return type of kvm_vcpu_preferred_target()"). Document what it returns,
that userspace selects vCPU features itself, and drop the error.

No functional change intended.
