sctp: Fix crc32c calculations on big-endian arhes.

crc32c algorithm provides a byteswaped result.  On little-endian
arches, the result ends up in big-endian/network byte order.
On big-endinan arches, the result ends up in little-endian
order and needs to be byte swapped again.  Thus calling cpu_to_le32
gives the right output.
