[Ada] Ignore Set_Priority of terminated task

Subject: [Ada] Ignore Set_Priority of terminated task

RM-D.5.1(7) requires Set_Priority on a terminated task to have no effect.
We were instead raising Tasking_Error. This patch corrects that behavior.

Tested on x86_64-pc-linux-gnu, committed on trunk

2009-09-17  Bob Duff  <duff@adacore.com>

	* a-dynpri.adb (Set_Priority): Don't do anything if the task is already
	terminated.
	(Get_Priority): Correct message for "terminated" case -- it said "null".
