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

[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 if the list is empty.

Fixes: 1666faedb567 ("software node: Add software_node_get_reference_args()")
