ada: Remove unneeded code in handling formal type defaults

Unneeded code found while experimenting with improved detection of
unreferenced objects.

gcc/ada/

	* sem_ch12.adb (Validate_Formal_Type_Default): Remove call to
	Collect_Interfaces, which had no effect apart from populating a
	list that was not used; fix style.
