[PATCH 1/2] board: phytec: phytec_som_detection: Add missing assignment

[Daniel Schultz]

Assign the return value of snprintf (total length) to a variable to
properly check if the string has the correct length.

Currently, this variable is always zero and the length check after
snprintf will always fail.
