cputlb: Fold TLB_RECHECK into TLB_INVALID_MASK
We had two different mechanisms to force a recheck of the tlb.
Before TLB_RECHECK was introduced, we had a PAGE_WRITE_INV bit
that would immediate set TLB_INVALID_MASK, which automatically
means that a second check of the tlb entry fails.
We can use the same mechanism to handle small pages.
Conserve TLB_* bits by removing TLB_RECHECK.
