[PATCH 10/13] sgi-gru: update to new mmu_notifier semantic

[jglisse]

From: JÃrÃme Glisse <jglisse@xxxxxxxxxx>

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.
