[PATCH v2 10/12] KVM: SVM: Do not throw warning when calling avic_vcpu_load on a running vcpu

[Suravee Suthikulpanit]

Originalliy, this WARN_ON is designed to detect when calling
avic_vcpu_load() on an already running vcpu in AVIC mode (i.e. the AVIC
is_running bit is set).

However, for x2AVIC, the vCPU can switch from xAPIC to x2APIC mode while in
running state, in which the avic_vcpu_load() will be called from
svm_refresh_apicv_exec_ctrl().

Therefore, remove this warning since it is no longer appropriate.
