mm: update mmu_gather range correctly
We use __tlb_adjust_range to update range convered by mmu_gather struct.
We later use the 'start' and 'end' to do a mmu_notifier_invalidate_range
in tlb_flush_mmu_tlbonly(). Update the 'end' correctly in
__tlb_adjust_range so that we call mmu_notifier_invalidate_range with
the correct range values.
Wrt tlbflush, this should not have any impact, because a flush with
correct start address will flush tlb mapping for the range.
Also add comment w.r.t updating the range when we free pagetable pages.
For now we don't support a range based page table cache flush.
