Pavel Hrdina a02fc0d022 virtManager: clone: build default clone path if we know how 
Function do_we_default returns only if we want to default to clone disk
even if we know how to create default clone path.  Only in case that the
storage pool is TYPE_DISK we don't know how to create default path and
we cannot default to clone that disk.  In all other cases as ReadOnly
disk or Shareable and so on we can prepare the default path for user if
they decide to clone it.
