context_dxinterop: lock rendertarget after present when swapping buffers

Browse Source 
Moves the DXLockObjectsNV call to after PresentEx. This fixes an issue
where the presented image is a single frame late. This may be due to
DXLockObjectsNV locking the render target before StretchRect is done.
The spec indicates that the lock call should provide synchronization
for the resource, so this may be due to a driver bug.
