Bing Niu 9baf0920b5 drm/i915/gvt: don't rely on guest PPGTT entry to free old shadow data
On guest writing a PPGTT entry, if it contains value and the old
entry is valid, gvt will read it and find & free the corresponding
old data for it. However, with the KVM write protection provided
by page_track, the guest entry will be written with new value
before gvt handling. To avoid that, we should use the shadow
entry instead.
