riscv: KVM: Fix hart suspend status check
[ Upstream commit c7db342e3b4744688be1e27e31254c1d31a35274 ]
"Not stopped" means started or suspended so we need to check for
a single state in order to have a chance to check for each state.
Also, we need to use target_vcpu when checking for the suspend
state.
