slab: correctly handle __GFP_ZERO
Use the correct local variable when calling into the page allocator. Local `flags' can have __GFP_ZERO set, which causes us to pass __GFP_ZERO into the page allocator, possibly from illegal contexts. The page allocator will later do prep_zero_page()->kmap_atomic(..., KM_USER0) from irq contexts and will then go BUG.
