[PATCH 6/7] wined3d: Always submit UPDATE_SUB_RESOURCE ops when uploading if not mapping persistently.

This is a bit unfortunate, because, but for this patch, we could get rid of
wined3d_map_persistent() entirely. On the other hand, this could potentially go
away if we change to a different scheme for determining when to unmap buffers.
