[COMMITTED] ada: Clean up copying of node trees

["Marc Poulhiès" <poulhies@adacore.com>]

From: Piotr Trojanek <trojanek@adacore.com>

Before calling routine In_Entity_Map we checked if the entity map is
present; inside this routine we checked this again.

Code cleanup; semantics is unaffected.

gcc/ada/

	* sem_util.adb (Update_New_Entities): Remove redundant check for entity
	map being present.

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