[PATCH 3/9] vt: selection, remove 2 local variables from set_selection_kernel

[Jiri Slaby <jslaby@suse.cz>]

multiplier and mode are not actually needed:
* multiplier is used only in kmalloc_array, so use "use_unicode ? 4 : 1"
  directly
* mode is used only to assign a bool in this manner:
  if (cond)
    x = true;
  else
    x = false;
  So do "x = cond" directly.
