Re: [libvirt PATCH] qemu_hotplug: don't forget to add hostdev interfaces to the interface list

Originally qemuDomainAttachNetDevice() would wait until the cleanup at the very end of the function to add newly hotplugged interfaces to the domain's nets list. commit 7b8bec4560 modified it to add the new interface to the nets list earlier (but not all the way at the beginning of the function either, because there are some operations (PCI address assignment in particular) that need the new device to not yet be visible in the domaindef). But hostdev interfaces short-circuit past most of the body of qemuDomainAttachNetDevice() (since none of it applies to hostdev interfaces). In the past that was okay, but since the line that adds the new interface to the domaindef's nets list is in that "most of the body", after that commit hotplugged hostdev interfaces are no longer being properly added to the domaindef nets list, so they don't show up in the status XML or the virsh domiflist output. It really *is* important to add interfaces to the nets list earlier, so we can't revert commit 7b8bec4560, and we also can't move the insert to common code *earlier* in the function, so instead this patch duplicates the VIR_APPEND_ELEMENT_COPY() just before the code path for hostdev interfaces jumps to cleanup. Resolves: https://bugzilla.redhat.com/1972991 Fixes: 7b8bec45601b6570f6a7413e94d291986d2663f1 (any other tags I should add?)
