Having explicit locators is not a sufficient condition to be able to have 

children for a pseudo-device.  Depending on an interface attribute is,
though.

Instead of looking at locators, walk the 'attrs' list and look for an
interface attribute (which might have been added just a few lines before
in case there was explicit locators defined).

Fixes PR#32329 by Valeriy E. Ushakov.  Regression test is PSEUDO_PARENT.
