Subject: [Ada] fix small race condition

Tested on i686-linux, committed on mainline.

There is a small race condition found while inspecting the code: it
may be possible that between the time a lock is released, and Set_Priority
is called, the priority value is changed in another task. This patch
fixes this potential race condition by saving the priority value while holding
lock.

	* s-tasren.adb (Exceptional_Complete_Rendezvous): Fix race condition.
