Haotian Zhang 6cd1441439 crypto: starfive - Correctly handle return of sg_nents_for_len

[ Upstream commit e9eb52037a529fbb307c290e9951a62dd728b03d ]

The return value of sg_nents_for_len was assigned to an unsigned long
in starfive_hash_digest, causing negative error codes to be converted
to large positive integers.

Add error checking for sg_nents_for_len and return immediately on
failure to prevent potential buffer overflows.
