When recursively clearing out disconnected pts, the range based TLB flush in handle_removed_tdp_mmu_page uses the wrong starting GFN, resulting in the flush mostly missing the affected range. Fix this by using base_gfn for the flush.
In response to feedback from David Matlack on the RFC version of this patch, also move a few definitions into the for loop in the function to prevent unintended references to them in the future.
