Remove unnecessary shutdown argument to _destroy()

Xen requires the VM power state be not running before it can be
destroyed. Xen also requires the VM power state to be running
to shutdown a VM. The shutdown argument was available to ensure
that a shutdown was not attempted when the VM was not running.

Since commit f5b051bbd0858294157f911ecbb04542fadbb38d, the
_shutdown() method checks the power state and determines if it
should issue the shutdown command or not. As a result, the
shutdown argument is unnecessary and always calling the
_shutdown() method will ensure the VM is in the proper state
for the destroy to succeed.

Defer image_ref update to manager on rebuild

We shouldn't update the DB and use it for passing the new image_ref for
a rebuild.  This causes a usage exists notification for the new image
instead of the old... and technically the new image is not accurate
until we shutdown the old instance and try building the new one..

Avoid unnecessary inst lookup in vmops _shutdown.

Updates the XenServer vmops.py _shutdown function so that it
avoids calling get_info/_get_vm_opaque_ref with the instance name.
Since _shutdown already has the vm_ref there is no need to make
this call.

This fixes an issue where 'RESIZE' was broken when resizing to
the same host.

Fixes LP Bug #997313.
