Fix an incompatible pointer passed to winbind_get_groups

This is the same bug that was fixed in other places of the code a few times
already:

A C compiler ONLY does automatic type conversions during an assignment.

Passing down a pointer to type A to a function taking type B as an
argument does NOT do any automatic type conversions.

If required, I can dig up the relevant portions of the C standard.
