Add one to esel values in h2g_tlb1_rmap, so that "no mapping" can be
distinguished from "esel 0". Note that we're not saved by the fact
that host esel 0 is reserved for non-KVM use, because KVM host esel
numbering is not the raw host numbering (see to_htlb1_esel).
or E500_TLB_VALID in TLB1.
Since we can have more than one host TLB entry for a given tlbe_ref,
be careful not to clear existing flags that are relevant to other
host TLB entries when preparing a new host TLB entry.

It's possible that we're using the same host TLB1 slot to map (a
presumably different portion of) the same guest TLB1 entry. Clear
the bit in the map before setting it, so that if the esels are the same
the bit will remain set.
