gsdx: check for null deference. 

CID 146839 (#1 of 1): Explicit null dereferenced (FORWARD_NULL)11. var_deref_model: Passing null pointer fb_pages to UsePages, which dereferences it.

CID 146840 (#1 of 1): Explicit null dereferenced (FORWARD_NULL)11. var_deref_model: Passing null pointer zb_pages to UsePages, which dereferences it.
