context_tracking: Fix KCSAN noinstr violation
With KCSAN enabled, even empty inline stubs can be out-of-lined.
Force the context_tracking_guest_exit() stub inline.
Fixes the following warnings:
vmlinux.o: warning: objtool: vmx_vcpu_enter_exit+0x1be: call to context_tracking_guest_exit() leaves .noinstr.text section
vmlinux.o: warning: objtool: svm_vcpu_enter_exit+0x85: call to context_tracking_guest_exit() leaves .noinstr.text section
