[1/2] WineD3D: Do not activate CTXUSAGE_BLIT for fb -> texture reading

[Stefan Dösinger]

Alexandre: please do not apply until Roderick confirms this is correct

This ActivateContext call slipped in with patch 
ba90a740beb9ce9a839cc843db8d87f5a37becdd. Roderick, was there a particular 
reason why you activate CTXUSAGE_BLIT here, or was it just a copypaste 
mistake from the glReadPixels codepath? None of the BLIT states *should* 
affect glCopyTexImage2D. As stated in the comment, the glReadPixel path sets 
it to work around some driver issues on Mesa, but I haven't seen a driver 
having issues with glCopyTexImage2D in that regard.

I came across this patch because it subtly broke offscreen rendering in Guild 
Wars(Linux nvidia). That's also not quite right since the states should be 
orthogonal to glCopyTexImage2D. I am having some issues on MacOS too.
