[PATCH 3/5] wined3d: Handle WINED3D_LOCATION_DISCARDED in wined3d_buffer_get_memory().

This can't currently happen. However, we'd like to use
wined3d_buffer_get_memory() in wined3d_cs_exec_update_sub_resource(). This would
probably also help in implementing ID3D11DeviceContext1::DiscardResource().
