[COMMITTED] ada: Simplify appending to a newly created list

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

From: Piotr Trojanek <trojanek@adacore.com>

Code cleanup; semantics is unaffected.

gcc/ada/

	* exp_disp.adb (Make_Disp_Asynchronous_Select_Spec): Use a single call
	to New_List.

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