When pmap_enter_pde() needs to destroy existing kernel superpage
mapping, do not remove saved pt page from the pm_root trie. Then the
pt page does not need to be re-inserted into the trie.
If the kernel region is not mapped with the superpage, try to insert the
pt page into pm_root trie before clearing ptes. If failed, we can
return failure without a need to rewind.
