Shuo Liu 4c4c1257b8 virt: acrn: Do hcall_destroy_vm() before resource release ... The ACRN hypervisor has scenarios which could run a real-time guest VM. The real-time guest VM occupies dedicated CPU cores, be assigned with dedicated PCI devices. It can run without the Service VM after boot up. hcall_destroy_vm() returns failure when a real-time guest VM refuses. The clearing of flag ACRN_VM_FLAG_DESTROYED causes some kernel resource double-freed in a later acrn_vm_destroy(). Do hcall_destroy_vm() before resource release to drop this chance to destroy the VM if hypercall fails.
