[PATCH v3 2/5] mmu_notifiers: Fixup comment in mmu_interval_read_begin()

[Alistair Popple]

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.
