[COMMITTED] ada: Add default value at initialization for CodePeer

[Marc Poulhiès via Gcc-patches]

From: Yannick Moy <m...@adacore.com>

Avoid spurious alarm by CodePeer analysis by adding default value
for a variable initialization.

gcc/ada/

        * sem_util.adb (Check_Node): Add default init on local Id.

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