x86/mm/pti: Make local symbols static

With 'make C=2 W=1', sparse and gcc both complain:

  CHECK   arch/x86/mm/pti.c
arch/x86/mm/pti.c:84:3: warning: symbol 'pti_mode' was not declared. Should it be static?
arch/x86/mm/pti.c:605:6: warning: symbol 'pti_set_kernel_image_nonglobal' was not declared. Should it be static?
  CC      arch/x86/mm/pti.o
arch/x86/mm/pti.c:605:6: warning: no previous prototype for 'pti_set_kernel_image_nonglobal' [-Wmissing-prototypes]
  605 | void pti_set_kernel_image_nonglobal(void)
      |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

pti_set_kernel_image_nonglobal() is only used locally. 'pti_mode' exists in
drivers/hwtracing/intel_th/pti.c as well, but it's a completely unrelated
local (static) symbol.

Make both static.
