Subject: Restore old BOUND_EXACT logic in qsearch

Restore old BOUND_EXACT logic in qsearch

In case a PvNode node has a static evaluation above alpha but
no available moves we want to flag the node as BOUND_EXACT,
not as BOUND_UPPER as is currently.

The behaviour was recently introduced with patch d471c49700fbe8281
of 3/10/2012

Spotted by Hongzhi Cheng.
