IB/hfi1: constify mmu_notifier_ops structure
Declare the structure mmu_notifier_ops as const as it is only stored in
the ops field of a mmu_notifier structure. The ops field is of type
const struct mmu_notifier_ops *, so mmu_notifier_ops structures having
this property can be declared as const.
Done using coccinelle:
@r1 disable optional_qualifier @
identifier i;
position p;

static struct mmu_notifier_ops i@p = {...};
@ok1@
identifier r1.i;
position p;
struct mmu_rb_handler handler;
