[PATCH 2/6] crypto: Fix scatterwalk_done() test.

[David Miller <davem@davemloft.net>]

We are done with the scattergather entry when the walk offset goes
past sg->offset + sg->length, not when it crosses a page boundary.

There is a similarly queer test in the second half of
scatterwalk_pagedone() that probably needs some scrutiny.
