[PATCH 5/7] wined3d: UpdateTexture requires a sysmem source and default destination

[Stefan Dösinger]

Note that this is already enforced for 2D and cube textures by
wined3d_device_update_surface.

Tests for this and follow-up patches can be found in the archive posted
to wine-devel at
http://www.winehq.org/pipermail/wine-devel/2013-August/100890.html. They
are next in my send queue.
