[node-patches] Change in ovirt-node[master]: Make sure $live_dev isn't an empty string

Change subject: Make sure $live_dev isn't an empty string
......................................................................

Make sure $live_dev isn't an empty string

Checking whether an empty string exists as a file appears to
always be true. Check whether it's empty as well, so we don't try
to use empty strings as $live_dev
