crypto: sahara - fix processing requests with cryptlen < sg->length

Browse source

[ Upstream commit 5b8668ce34 ]

It's not always the case that the entire sg entry needs to be processed.
Currently, when cryptlen is less than sg->legth, "Descriptor length" errors
are encountered.

The error was noticed when testing xts(sahara-ecb-aes) with arbitrary sized
input data. To fix this, take the actual request size into account when
populating the hw links.
