Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred

It does not make sense to pass file variable (which is NULL) to function
save_err_ptr_str() which converts its argument to string. We can call
directly save_err_str() with string value.

Also it is highly unexpected that GetModuleHandle(NULL) call fails.
