mmu_notifiers: fixup comment in mmu_interval_read_begin()

Browse source 
The comment in mmu_interval_read_begin() refers to a function that doesn't
exist and uses the wrong call-back name.  The op for mmu interval
notifiers is mmu_interval_notifier_ops->invalidate() so fix the comment up
to reflect that.
