[Ada] Fix thinko in Acc_Loop_to_gnu 

This fixes a glitch introduced during the initial OpenACC work import
process, causing crashes on any Acc_Parallel + Acc_Loop combination.

2019-08-19  Olivier Hainque  <hainque@adacore.com>

gcc/ada/

	* gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
	BIND_EXPR node we have constructed on purpose.  Remove unused
	variable.

gcc/testsuite/

	* gnat.dg/openacc1.adb: New testcase.
