[PATCH 2/3] wined3d: Clear the BO map_ptr in wined3d_bo_gl_unmap() even if the chunk is still mapped.

If we subsequently try to destroy it we will decrease the chunk map_count again, which is a reference counting error.

[PATCH 3/3] wined3d: Respect the client map count even for suballocated BOs.

[Zebediah Figura]

From: Zebediah Figura

I believe this was a mistake introduced by 831ff102008e2ba93a403344646b5ed67258eaeb.

This fixes GL errors with multiple applications, including Ragnarok Online and
Bloodrayne: Terminal Cut.
