LoongArch/crypto: Clean up useless assignment operations
The LoongArch CRC32 hw acceleration is based on arch/mips/crypto/ crc32-mips.c. While the MIPS code supports both MIPS32 and MIPS64, but LoongArch32 lacks the CRC instruction. As a result, the line "len -= sizeof(u32)" is unnecessary. Removing it can make context code style more unified and improve code readability.
