crypto: mips/crc32 - fix the CRC32C implementation

Commit ca459e5 ("crypto: mips/crc32 - Clean up useless assignment
operations") changed crc32c_mips_le_hw() to use the instructions that
use the "regular" CRC32 polynomial instead of the Castagnoli polynomial.
Therefore it can't be computing CRC32C values correctly anymore.

I haven't been successful in running a MIPS kernel in QEMU, but based on
code review this is the fix that is needed.
