Subject: [PATCH 06/13] IB/hfi1: update to new mmu_notifier semantic

From: Jérôme Glisse <jglisse@...hat.com>

Call to mmu_notifier_invalidate_page() are replaced by call to
mmu_notifier_invalidate_range() and thus call are bracketed by
call to mmu_notifier_invalidate_range_start()/end()

Remove now useless invalidate_page callback.
