In preparing to remove all stack VLA usage from the kernel[1], this removes the discouraged use of AHASH_REQUEST_ON_STACK in favor of the smaller SHASH_DESC_ON_STACK by converting from ahash-wrapped-shash to direct shash. By removing a layer of indirection this both improves performance and reduces stack usage. The stack allocation will be made a fixed size in a later patch to the crypto subsystem. The bulk of the lines in this change are simple s/ahash/shash/, but the main logic differences are in drbd_csum_ee() and drbd_csum_bio(), which externalizes the page walking with k(un)map_atomic() instead of using scattergather.
