x86: fix csum_ipv6_magic asm memory clobber
commit 392d814daf460a9564d29b2cebc51e1ea34e0504 upstream.
Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a
memory clobber, as it is only passed the address of the buffer, not a
memory reference to the buffer itself.
This caused failures in Hurd's pfinetv4 when we tried to compile it with
gcc-4.3 (bogus checksums).
