[COMMITTED] ada: Cleanup getting of actual subtypes

[Marc Poulhiès]

From: Piotr Trojanek <trojanek@adacore.com>

Avoid potentially unnecessary call to Etype.

gcc/ada/

	* sem_util.adb (Get_Actual_Subtype_If_Available): Only call Etype
	when necessary.

Tested on x86_64-pc-linux-gnu, committed on master.
