This patch fixes a severe bug in vtlb, where domU may face machine crash
intermittently. Normally in page fault handler, the entry hit in vtlb shouldn't
be injected back to vtlb again, not to say meaningless -1UL. After this fix,
vtlb hit ratio also improves since guest svhpt entry may live longer.
