Marc Mutz 198768cbba QWidget: fix expensive iteration over QMap::keys() 
... with iteration over the hash itself.

Can't keep the call to ungrabGesture() in the loop,
because it removes the current element from the very
hash being iterated over. Instead, inline the call
and optimize based on the context:

- don't remove element by element, but clear the
  hash completely at the end.
- drag the check for QGestureManager::instance()
  out of the loop.
- drop the check for presence of the key in the
  hash, since it would be always true.
