[PATCH v3 1/2] software node: Initialize the return value in software_node_to_swnode()

[Heikki Krogerus]

The software node is searched from a list that may be empty
when the function is called. This makes sure that the
function returns NULL even if the list is empty.

Fixes: 80488a6b1d3c ("software node: Add support for static node descriptors")
