m68k/mm: use correct bit number in _PAGE_SWP_EXCLUSIVE comment
As noticed by Geert, commit b5c88f21531c ("microblaze/mm: support
__HAVE_ARCH_PTE_SWP_EXCLUSIVE") modified m68k code by accident. While
replacing 0x080 by CF_PAGE_NOCACHE is correct, although it should have
been part of commit ed4154067a08 ("m68k/mm: support
__HAVE_ARCH_PTE_SWP_EXCLUSIVE"), replacing "bit 7" by "bit 24" in the
comment was wrong.
Let's revert to the previous, correct, comment.
