[COMMITTED] ada: Cleanup redundant condition in resolution of entity names

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

From: Piotr Trojanek <trojanek@adacore.com>

Code cleanup related to new contract for SPARK; semantics is unaffected.

gcc/ada/

	* sem_res.adb (Resolve_Entity_Name): Combine two IF statements that
	execute code only for references that come from source.

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