s390/crypto: fix compile error for ChaCha20 module
The clgfi instruction used within the ChaCha20 assembly is only
available for z9-109 and newer machines, and therefore this will
generate a compile error if compiled e.g. with MARCH_Z900.
Given that the assembler code will only be executed on machines with
vector instructions, which became much later available than z9-109,
use insn notation to generate the clgfi instruction, and avoid compile
errors due to unknown instructions.
