wined3d: call glFinish before performing a discard map

This is a test patch to confirm my theory from comment 30. Note that you have
to enable strict draw ordering for this patch to work. If my theory is correct
this patch(without any other patches) should fix the flickering.

Note that this is not a proper fix. It has a pretty big performance impact. In
fact it has a bigger performance impact than simply ignoring D3DLOCK_DISCARD.
