Subject: [PATCH] agp/intel: Destroy the scatterlist on allocation failure

A side-effect of being able to use custom page allocations with the
sg_table is that it cannot reap the partially constructed scatterlist if
fails to allocate a page. So we need to call sg_free_table() ourselves
if sg_alloc_table() fails.
