util: Fix le128_to_cpu on little-endian

We need to swap the words order in little-endian machine too.
For example:

uint128:  0x4000000030000000200000001

 0  1  2  3 |  4  5  6  7 | 8  9  a  b  | c  d  e  f
01 00 00 00 | 02 00 00 00 | 03 00 00 00 | 04 00 00 00

  w0(MSB)   |     w1      |    w2       |  w3(LSB)
04 00 00 00 | 03 00 00 00 | 02 00 00 00 | 01 00 00 00
