ARM/boot: Don't poison 'current' during early boot

This logic was inherited from x86 (which was updated several times since).
Unlike x86 (at the time) however, while NULL isn't mapped in ARM, 0xfffff000
is, making this actively dangerous.

Drop the logic entirely, and leave 'current' as NULL during early boot.
