Fix NULL check

Detect callback message could be null.

WID:62132701 After having been assigned to a NULL value at
mv_barcode_detect_open.cpp:240, pointer '0' is passed as 4th parameter
in call to function 'barcode_detected_cb' at
mv_barcode_detect_open.cpp:240, where it is dereferenced at
test_barcode.cpp:25.
