[PATCH 2/5] nohz: add stub context_tracking_is_enabled

[riel@redhat.com]

From: Rik van Riel <riel@redhat.com>

With code elsewhere doing something conditional on whether or not
context tracking is enabled, we want a stub function that tells us
context tracking is not enabled, when CONFIG_CONTEXT_TRACKING is
not set.
