crypto: mips/crc32 - Clean up useless assignment operations
When entering the "len & sizeof(u32)" branch, len must be less than 8.
So after one operation, len must be less than 4.
At this time, "len -= sizeof(u32)" is not necessary for 64-bit CPUs.
After that, replace `while' loops with equivalent `for' to make the
code structure a little bit better by the way.
