Sami Tolvanen 0f186b1e6e ANDROID: kthread: cfi: disable callback pointer check with modules ...

With CFI, a callback function passed to __kthread_queue_delayed_work
from a module can point to a jump table entry defined in the module
instead of the one used in the core kernel, which breaks this test:

  WARN_ON_ONCE(timer->function != kthread_delayed_work_timer_fn);

To work around the problem, disable the warning when CFI and modules
are both enabled.
