virsh: Do not check the input XML at virsh layer for cmdDetachDevice

Any device XML doesn't use the same order as libvirt generates, or
uses decimal for attributes like "slot" of "<address>" will cause
device detaching to fail, as virsh compares the XML simply earlier
in strict manner before internal parsing.

This is regression introduced by ea7182c.
