LA57/PKE/PKS is only relevant in 64-bit mode, and NXE is only relevant if PAE is in use. Since there is code that checks PG_MODE_LA57 to determine the canonicality of addresses, make sure that the bit is not set by mistake in 32-bit mode. While it would not be a problem because 32-bit addresses by definition fit in both 48-bit and 57-bit address spaces, it is nicer if get_pg_mode() actually returns whether a feature is enabled, and it allows a few simplifications in the page table walker.
