board-inspector: fix a branch condition that checks existence of HWP

Browse Source 
Evaluating an XPATH on a tree results an empty list (rather than None) when
that tree does not contain any matching node. This patch fixes a branch
condition that does not check the XPATH evaluation result properly.

Tracked-On: #8168
