ipv6: fix sparse warnings in privacy stable addresses generation

Browse source 
Those warnings reported by sparse endianness check (via kbuild test robot)
are harmless, nevertheless fix them up and make the code a little bit
easier to read.

Reported-by: kbuild test robot <fengguang.wu@intel.com>
Fixes: 622c81d57b ("ipv6: generation of stable privacy addresses for link-local and autoconf")
