Herbert Xu 4f3e797ad0 crypto: scatterwalk - Avoid flush_dcache_page on slab pages
It's illegal to call flush_dcache_page on slab pages on a number
of architectures.  So this patch avoids doing so if PageSlab is
true.

In future we can move the flush_dcache_page call to those page
cache users that actually need it.
