virtio-crypto: verify src&dst buffer length for sym request
For symmetric algorithms, the length of ciphertext must be as same as the plaintext. The missing verification of the src_len and the dst_len in virtio_crypto_sym_op_helper() may lead buffer overflow/divulged. This patch is originally written by Yiming Tao for QEMU-SECURITY, resend it(a few changes of error message) in qemu-devel.
