For nested virt we maintain multiple VMCS that can run on a vCPU. So it is incorrect to keep vmcs_host_cr3 and vmcs_host_cr4, whose purpose is caching the value of the rarely changing HOST_CR3 and HOST_CR4 VMCS fields, in vCPU-wide data structures. Hyper-V nested on KVM runs into this consistently for me with PCID enabled. CR3 is updated with a new value, unlikely(cr3 != vmx->host_state.vmcs_host_cr3) fires, and the currently loaded VMCS is updated. Then we switch from L2 to L1 and the next exit reverts CR3 to its old value.

The only bad consequence of this now is that avic_vm_destroy() uses svm_vm_data_hash_lock that hasn't been initialized (and is not meant to be used at all if avic is not enabled). Return early from avic_vm_destroy() if avic is not enabled. It has nothing to destroy.
