Haotian Zhang f57925f0c4 crypto: ccree - Correctly handle return of sg_nents_for_len 
[ Upstream commit 8700ce07c5 ]

Fix error handling in cc_map_hash_request_update where sg_nents_for_len
return value was assigned to u32, converting negative errors to large
positive values before passing to sg_copy_to_buffer.

Check sg_nents_for_len return value and propagate errors before
assigning to areq_ctx->in_nents.
