sparc64: extend TI_RESTART_BLOCK space by 8 bytes

Impact: build fix

Today's linux-next build (sparc64 defconfig) failed like this:

  arch/sparc/kernel/built-in.o: In function `trap_init':
  (.init.text+0x4): undefined reference to `thread_info_offsets_are_bolixed_dave'

Caused by commit 52400ba946759af28442dee6265c5c0180ac7122 ("futex: add
requeue_pi functionality") (from the tip-core tree) which changed the
size of struct restart_block.

Shift TI_KUNA_REGS and TI_KUNA_INSN up by 8 bytes to make space for the
larger restart block.
