[PATCH] m68k: fix conditional use of init_pointer_table

From: Greg Ungerer <[email protected]>

Compiling 3.8-rc1 fails for some m68k targets (the non-mmu ones) with:

  CC      arch/m68k/mm/init.o
arch/m68k/mm/init.c: In function ‘mem_init’:
arch/m68k/mm/init.c:191:2: error: implicit declaration of function ‘init_pointer_table’

make[1]: *** [arch/m68k/mm] Error 2
make[1]: Leaving directory `/home/gerg/new-wave.git/linux-3.x'
make: *** [linux] Error 1

Change the conditions that define init_pointer_table so that it matches what
actually uses it.
