net: move backend cleanup to NIC cleanup
Commit a0d7215e33 ("vhost-vdpa: do not cleanup the vdpa/vhost-net
structures if peer nic is present") effectively delayed the backend
cleanup, allowing the frontend or the guest to access it resources as
long as the frontend is still visible to the guest.
However it does not clean up the resources until the qemu process is
over. This causes an effective leak if the device is deleted with
device_del, as there is no way to close the vdpa device. This makes
impossible to re-add that device to this or other QEMU instances until
the first instance of QEMU is finished.
Move the cleanup from qemu_cleanup to the NIC deletion and to
net_cleanup.
Fixes: a0d7215e33 ("vhost-vdpa: do not cleanup the vdpa/vhost-net structures if peer nic is present")
