We can remove this now.
Previous to this patchset the post notifier would run in interrupt
context hence we couldnt call user_disable_single_step

However from this patchset, (due to changes to do away with per task
slot), we run the post notifier in task context. Hence we can now call
user_enable_single_step/user_disable_single_step which does the right
thing. 

Please correct me if I am missing.
