tools/cgxset: fix Coverity uninitialized variable warning

Originally this issue got reported on tools/cgset and since tools/cgxset
borrows most of the code from cgset, fix the issue here too.  The
original warning (cgset):

CID 1488715 (#1 of 1): Uninitialized scalar variable (UNINIT).
uninit_use_in_call: Using uninitialized value *src_cg_path as
argument to %s when calling fprintf.
