Subject: [PATCH] qemu_command: don't modify heads for graphics device

Setting heads to 0 in case that *max_outputs* is not supported while building
command line doesn't have any real effect.  It only removes *heads* attribute
from live XML, but after restarting libvirt the default value is restored.
