A method which has keyword parameters has an implicit local variable
to specify which keywords are (un)specified.
vm_call_iseq_setup_kwparm_nokwarg() is special function to invoke
a ISeq method without any keyword arguments. However, it should
also initialize the special local var. Without this initialization,
the implicit lvar can points a freed (T_NONE) object.
