Use the sg count returned by dma_map_sg to call into
dmaengine_prep_slave_sg rather than using the original sg count. dma_map_sg
can merge consecutive sglist entries, thus making the original sg count
wrong. This is a fix for memory coruption issues observed while testing
encryption/decryption of large messages using libkcapi framework.
Patch has been tested further by running full suite of tcrypt.ko tests
including fuzz tests.

The default DRBG is the one that has the highest priority. The priority
is defined based on the order of the list drbg_cores[] where the highest
priority is given to the last entry by drbg_fill_array.
With this patch the default DRBG is switched from HMAC SHA256 to HMAC
SHA512 to support compliance with SP800-90B and SP800-90C (current
draft).
