ACPICA: Fix for hang on GPE method invocation

Browse Source 
Fixes problem where the new method argument count validation mechanism
will enter an infinite loop when a GPE method is dispatched.
Problem fixed be removing the obsolete code that passes GPE block
information to the notify handler via the control method parameter pointer.
