Johanna Amann 24f74cb52e Fix alignment issue of ones_complement_checksum 
The ones_complement_checksum function assumes that the bytes passed into
it are aligned on 16 bit boundaries.

When using gcc (GCC) 6.2.1 20160916 (Red Hat 6.2.1-2) with -O2, this
does not seem to hold true anymore; assuming 16 bit alignment will lead
to accesses to uninitialized memory and wrong checksums.

This commit adds a minimally invasive change that does not assume
alignment anymore. This might have a small performance impact for every
single packet we process.

This error occured reproducibly when called from icmp6_checksum.
