after hot-unplug,
the virtio-blk would turn on and then back off.
So this patch set the Link Status inactive after hot-unplug and
active after hot-plug.

The elements of kvm_devices_head list are freed in kvm_arm_machine_init_done(),
but we still access these illegal memory in kvm_arm_devlistener_del().
This will cause segment fault when booting guest with MALLOC_PERTURB_=1.

target/arm/kvm.c
using qemu
with vhost-scsi, it will fail with below error:
qemu-kvm: Error start vhost dev
qemu-kvm: unable to start vhost-scsi: Cannot allocate memory
This patch fix this issue by skipping calling vhost_virtqueue_start
for uninitialized queues.
