arm64 sys_membarrier number is already wired for arm64 through
asm-generic/unistd.h, but needs to be allocated separately for
the 32-bit compability layer of arm64.

[ Untested on this architecture. To try it out: fetch linux-next/akpm,
  apply this patch, build/run a membarrier-enabled kernel, and do make
  kselftest. ]
