  The LoongArch CRC32 hw acceleration is based on
arch/mips/crypto/crc32-mips.c. While the MIPS code supports both
MIPS32 and MIPS64, LA32 lacks the CRC instruction. As a result,
"line len -= sizeof(u32)" is unnecessary.

Removing it can make context code style more unified and improve
code readability.
