lib/mpi: Endianness fix

commit 3ee0cb5fb5eea2110db1b5cb7f67029b7be8a376 upstream.

The limbs are integers in the host endianness, so we can't simply
iterate over the individual bytes. The current code happens to work on
little-endian, because the order of the limbs in the MPI array is the
same as the order of the bytes in each limb, but it breaks on
big-endian.
