crypto: skcipher - Use scatterwalk (un)map interface for dst and src buffers
The skcipher walk API implementation avoids scatterwalk_map() for
mapping the source and destination buffers, and invokes kmap_atomic()
directly if the buffer in question is not in low memory (which can only
happen on 32-bit architectures). This avoids some overhead on 64-bit
architectures, and most notably, permits the skcipher code to run with
preemption enabled.
Now that scatterwalk_map() has been updated to use kmap_local(), none of
this is needed, so we can simply use scatterwalk_map/unmap instead.
