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.
