RISC-V: KVM: Allow memslots ending at the GPA limit

Browse source

KVM memslots describe half-open ranges [base_gfn, base_gfn + npages). A
slot ending exactly at the guest physical-address limit has its final page
below that limit and is valid.

The current greater-than-or-equal comparison rejects a valid boundary case.
Use a strict greater-than comparison, matching equivalent KVM architecture
checks.
