Subject: [PATCH] Fix clang static analyzer warning

A possible use of null pointer has been identified by clang static
analyzer:

    ../src/util.c:809:8: warning: Null pointer passed as an argument to a 'nonnull' parameter
                            if (strcmp (ver, lver) != 0) {
                                ^~~~~~~~~~~~~~~~~~
    1 warning generated.

Add a NULL pointer check to fix the warning.
