crc32: Correct endianness of crc32 result
When crc32 is handled by the hash library, it requires the data to be in big-endian format, since it reads it byte-wise. Thus at present the 'crc32' command reports incorrect data. For example, previously we might see: Peach # crc32 40000000 100 CRC32 for 40000000 ... 400000ff ==> 0d968558 but instead with the hash library we see: Peach # crc32 40000000 100 CRC32 for 40000000 ... 400000ff ==> 5885960d Correct this.
