x86-64: don't set the early IDT to point directly to 'early_idt_handler'
The code requires the use of the proper per-exception-vector stub functions (set up as the early_idt_handlers array - note the 's') that make sure to set up the error vector number. This is true regardless of whether CONFIG_EARLY_PRINTK is set or not. Why? The stack offset for the comparison of __KERNEL_CS won't be right otherwise, nor will the new check (from commit 8170e6be: "x86, 64bit: Use a #PF handler to materialize early mappings on demand") for the page fault exception vector.
