smp: add missing init.h include

Commit 34db18a054c6 ("smp: move smp setup functions to kernel/smp.c")
causes this build error on s390 because of a missing init.h include:

  CC      arch/s390/kernel/asm-offsets.s
  In file included from /home2/heicarst/linux-2.6/arch/s390/include/asm/spinlock.h:14:0,

  from arch/s390/kernel/asm-offsets.c:10:
  include/linux/smp.h:117:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'setup_nr_cpu_ids'
  include/linux/smp.h:118:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'smp_init'

Fix it by adding the include statement.
