crypto: sahara - fix processing hash requests with req->nbytes < sg->length

Browse source

[ Upstream commit 7bafa74d1b ]

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

To fix this, take the actual request size into account when populating the
hw links.
