Huacai Chen 619b52777a LoongArch: Fix kernel_page_present() for KPRANGE/XKPRANGE ...

Now kernel_page_present() always return true for KPRANGE/XKPRANGE
addresses, this isn't correct because hibernation (ACPI S4) use it
to distinguish whether a page is saveable. If all KPRANGE/XKPRANGE
addresses are considered as saveable, then reserved memory such as
EFI_RUNTIME_SERVICES_CODE / EFI_RUNTIME_SERVICES_DATA will also be
saved and restored.

Fix this by returning true only if the KPRANGE/XKPRANGE address is in
memblock.memory.
