Unlike no4lvl, no5lvl still continues detect satp, which requires va=pa mapping. When pa=0x800000000000, no5lvl would fail in Sv48 mode due to an illegal VA value of 0x800000000000. So, prevent detecting the satp flow for no5lvl, when vaddr is invalid. Add the is_vaddr_valid() function for checking.
