mm/mmu_notifier: convert user range->blockable to helper function
Use the mmu_notifier_range_blockable() helper function instead of directly
dereferencing the range->blockable field. This is done to make it easier
to change the mmu_notifier range field.
This patch is the outcome of the following coccinelle patch:

FN(..., struct mmu_notifier_range *I1, ...) {
