LoongArch/crypto: Clean up useless assignment operations
[ Upstream commit fea1c949f6
]
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.
