Calling unaligned/access-ok.h version of put_unaligned_le64()
causes data abort in arm 32-bit QEMU.

The similar issue also occurs in linux kernel,
unaligned/access-ok.h is no longer used in linux kernel[1].

This commit uses the unaligned/be_byteshift.h and
unaligned/le_byteshift.h helper instead of unaligned/access-ok.h.
