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.
