build: add explicit vars init to silence LTO related warning

Browse Source 
When Link Time Optimization is enabled, compiler can sometimes produce
additional warnings saying that some variables may be uninitialized.

To supress the warning it is enough to add explicit initialization
of the variable causing the issue, in this case '*module_name = NULL'
and "*writer = NULL".
