Zheng Wang 1022519da6 drm/i915/gvt: fix double free bug in split_2MB_gtt_entry ... [ Upstream commit 4a61648af6 ] If intel_gvt_dma_map_guest_page failed, it will call ppgtt_invalidate_spt, which will finally free the spt. But the caller function ppgtt_populate_spt_by_guest_entry does not notice that, it will free spt again in its error path. Fix this by canceling the mapping of DMA address and freeing sub_spt. Besides, leave the handle of spt destroy to caller function instead of callee function when error occurs.
