sched/core: Drop the unused try_get_task_struct() helper function

Browse Source 
This function was introduced by:

  150593bf86 ("sched/api: Introduce task_rcu_dereference() and try_get_task_struct()")

... to allow easier usage of task_rcu_dereference(), however no users
were ever added. Drop the helper.
