Sashiko (locally) reports a logical issues in mmio_guard_ioremap_hook()
mmio_guard_ioremap_hook() attempts to handle unaligned addresses and
sizes. However, aligning the start address before adding the size, might
shift the end to the page before.
Fixes: 0f12694958 ("drivers/virt: pkvm: Intercept ioremap using pKVM MMIO_GUARD hypercall")
