KVM: x86: Fully defer to vendor code to decide how to force immediate exit
Now that vmx->req_immediate_exit is used only in the scope of
vmx_vcpu_run(), use force_immediate_exit to detect that KVM should usurp
the VMX preemption to force a VM-Exit and let vendor code fully handle
forcing a VM-Exit.
Opportunsitically drop __kvm_request_immediate_exit() and just have
vendor code call smp_send_reschedule() directly. SVM already does this
when injecting an event while also trying to single-step an IRET, i.e.
it's not exactly secret knowledge that KVM uses a reschedule IPI to force
an exit.
