ada: Fix regression in Root_Type -- adjustment

Recent changes "Fix regression in Root_Type" and
"Crash on b3a1004 with assertions enabled" are partially
redundant; they are addressing the same bug.
This patch adjusts the former in the case of Root_Type.
But we leave Root_Type_If_Set alone; debugging printouts
should survive bugs when possible.

gcc/ada/ChangeLog:

	* einfo-utils.adb (Root_Type): Do not deal with missing Etype.
