crypto: virtio/akcipher - Fix stack overflow on memcpy
commit c0ec2a712daf133d9996a8a1b7ee2d4996080363 upstream.
sizeof(struct virtio_crypto_akcipher_session_para) is less than
sizeof(struct virtio_crypto_op_ctrl_req::u), copying more bytes from
stack variable leads stack overflow. Clang reports this issue by
commands:
make -j CC=clang-14 mrproper >/dev/null 2>&1
make -j O=/tmp/crypto-build CC=clang-14 allmodconfig >/dev/null 2>&1
make -j O=/tmp/crypto-build W=1 CC=clang-14 drivers/crypto/virtio/
virtio_crypto_akcipher_algs.o
