gimple-ssa-warn-access: add missing auto_diagnostic_group

Spotted whilst implementing nesting support in the
experimental-html diagnostic sink.

gcc/ChangeLog:
	* gimple-ssa-warn-access.cc
	(pass_waccess::maybe_check_dealloc_call): Add missing
	auto_diagnostic_group to nest the "returned from %qD"
	note within the warning.
