Subject: [PATCH] Fix SM4-XTS aarch64 assembly implementation bug

When macro VPSM4_CAPABLE or VPSM4_EX_CAPABLE is enabled,
the GB variant of the SM4-XTS algorithm will encounter errors when
encrypting or decrypting messages with a length greater than 16
bytes but less than 32 bytes.

The OpenSSL has similar issue,  the corresponding
solutions can be found in this [PR]
(https://github.com/openssl/openssl/pull/23317).
