Subject: [PATCH 2/6] FinishAccess_CS: set bo_mapped to FALSE on unmap

This is actually only necessary when PrepareAccess may behave differently on
different calls with the same pixmap, which currently doesn't happen.

However resetting bo_mapped is necessary to let PrepareAccess (with mixed
pixmaps) choose to fail based on whether the pixmap is in VRAM (to avoid CPU
reads).
