x86/boot: drop pre-C IDT patching

It is not needed now that __start_xen sets itself up with complete trap
handlers as its first action.  This fixes a potential issue introduced in

  c/s 7e510a7b874
  "x86/boot: move some __high_start code and data into init sections"

which would leave ignore_int (in the .init section) patched into the reserved
exceptions in all IDTs.
