pylibsmb: fix cast warnings in Python method definitions

Fix the following cast warnings in Python method definitions:

../../source3/libsmb/pylibsmb.c:1867:28: warning: cast between incompatible
function types from ‘PyObject * (*)(struct py_cli_notify_state *, PyObject *,
PyObject *)’ {aka ‘struct _object * (*)(struct py_cli_notify_state *, struct
_object *, struct _object *)’} to ‘PyObject * (*)(PyObject *, PyObject *)’
{aka ‘struct _object * (*)(struct _object *, struct _object *)’}
[-Wcast-function-type]
 1867 |                 .ml_meth = (PyCFunction)py_cli_notify_get_changes,
      |                            ^
