crypto: morus/generic - fix for big endian systems
commit 5a8dedfa3276e88c5865f265195d63d72aec3e72 upstream.
Omit the endian swabbing when folding the lengths of the assoc and
crypt input buffers into the state to finalize the tag. This is not
necessary given that the memory representation of the state is in
machine native endianness already.
This fixes an error reported by tcrypt running on a big endian system:
