[autotest] Handle empty DUT repair recommendations.

In the lab_inventory script, if repair recommendations were
requested, but no DUTs needing repair were found, the list of
recommendations would be `None`, leading to an exception.

Fix the handling to print useful output when the recommendations
list is empty.

BUG=None
TEST=run the command manually
