context_tracking: Tag context_tracking_enabled_this_cpu() __always_inline

Browse Source 
Force context_tracking_enabled_this_cpu() to be inlined so that invoking
it from guest_context_enter_irqoff(), which KVM uses in non-instrumentable
code, doesn't unexpectedly leave a noinstr section.

  vmlinux.o: warning: objtool: vmx_vcpu_enter_exit+0x1c7: call to
    context_tracking_enabled_this_cpu() leaves .noinstr.text section
  vmlinux.o: warning: objtool: svm_vcpu_enter_exit+0x83: call to
    context_tracking_enabled_this_cpu() leaves .noinstr.text section

Note, the CONFIG_CONTEXT_TRACKING_USER=n stub is already __always_inline.
