Subject: [PATCH v4 0/5] KVM: MMU: fix release no-slot pfn and clean up mmu
 code

Changlog:
- filter error pfn out in the common function - kvm_release_pfn instead
  of doing it in mmu code
- remove the patches which clean up for release noslot pfn path

Release pfn in the mmu code is little special for we allow no-slot pfn
go to spte walk on page fault path, that means, on page fault fail path,
we can not directly call kvm_release_pfn_clean.

This patchset fixes the bug which adds a branch to filter error pfn out
in kvm_release_pfn_clean and clean up current mmu code.
