[PATCH v2 17/43] KVM: x86: Directly block (instead of "halting") UNINITIALIZED vCPUs

[Sean Christopherson]

Go directly to kvm_vcpu_block() when handling the case where userspace
attempts to run an UNINITIALIZED vCPU.  The vCPU is not halted, nor is it
likely that halt-polling will be successful in this case.
