alpha: fix alignment problem in csum_ipv6_magic()

Hopefully this fixes http://bugzilla.kernel.org/show_bug.cgi?id=8635

The struct in6_addr passed to csum_ipv6_magic() is 4 byte aligned, so we
can't use the regular 64-bit loads.  Since the cost of handling of 4 byte
and 1 byte aligned 64-bit data is roughly the same, this code can cope with
any src/dst [mis]alignment.
