x86/idt: Remove address argument from idt_invalidate()
There is no reason to specify any specific address to idt_invalidate(). It
looks mostly like an artifact of unifying code done differently by
accident. The most "sensible" address to set here is a NULL pointer -
virtual address zero, just as a visual marker.
This also makes it possible to mark the struct desc_ptr in idt_invalidate()
as static const.
