Jan H. Schönherr 2f173d2688 KVM: x86: Fix immediate_exit handling for uninitialized AP 
When user space sets kvm_run->immediate_exit, KVM is supposed to
return quickly. However, when a vCPU is in KVM_MP_STATE_UNINITIALIZED,
the value is not considered and the vCPU blocks.

Fix that oversight.

Fixes: 460df4c1fc ("KVM: race-free exit from KVM_RUN without POSIX signals")
