[virt-tools-list] [PATCH v2 2/3] cpu: add helper function to reset cpu related variables to none

[Guannan Ren]

The helper function aims to reset cpu related vars to none except
<topology>.
It is named with clear_attrs(). clear() could be saved for later use
of clearing all of them including <topology>.
