Mention SR-IOV cold migration limitation in admin docs
It wasn't possible to perform a cold migration with SR-IOV devices attached to a server until Newton. This adds a mention of that limitation in the admin docs on PCI pass-through. Since the note this is going into already has a known limitation, it's re-formatted to be a list for readability and emphasis.
