powerpc/mm/64s: Fix no previous prototype warning 



As reported by lkp:

  arch/powerpc/mm/book3s64/radix_tlb.c:646:6: warning: no previous
  prototype for function 'exit_lazy_flush_tlb'

Fix it by moving the prototype into the existing header.

Fixes: 032b7f08 ("powerpc/64s/radix: serialize_against_pte_lookup IPIs trim mm_cpumask")
