mmu_page_remove_parent_pte() does much maintenance works,
but kvm_mmu_unlink_parents() unlink all parents, so
such maintenance works are not need.
This patch simplifies the works of kvm_mmu_unlink_parents()
by unlinking parents without so many maintenance works.

Joerg,
Would you like to add support on svm? I don't know the exact point to trigger

Yes I will do that, thanks for all
The current uio and uio_pci_generic allow multiple opens; I was just preserving
that behavior.

Ok Marcelo, test looks good, applied.
Thanks!
Adjust savevm_delay/guest memory size to reduce run time, if
excessive.
