Fault mitigation won't work in non-threaded code due to the following
error:
assertion 'ct >= 0 && ct < CFG_NUM_THREADS' failed at core/arch/arm/kernel
/thread.c:799 <thread_get_id>
The problem is in __ftmn_get_tsd_func_arg_pp which calls thread_get_tsd
which thread_get_id. The reason is that the interrupt handler is not
associated with any thread, so the ct (current_thread_id) value is -1 which
would cause an assert problem.
The fix is to add ftmn_arg to thread_core_local and the new variable would
be used when the current thread is < 0.
