core: Set ctx in global_xlator to prevent NULL ptr reference

This results in a crash in STACK_UNWIND after a call bail out.
Since the call bail does not occur in the context of an xlator,
the old_THIS in STACK_UNWIND is handed a global_xlator which did
not have its ctx set, resulting in a NULL de-reference.
