Andreea-Cristina Bernat 35b123e2f7 sched/fair: Replace rcu_assign_pointer() with RCU_INIT_POINTER() ...

The use of "rcu_assign_pointer()" is NULLing out the pointer.
According to RCU_INIT_POINTER()'s block comment:

  "1.   This use of RCU_INIT_POINTER() is NULLing out the pointer"

it is better to use it instead of rcu_assign_pointer() because it has a
smaller overhead.

The following Coccinelle semantic patch was used:

 - rcu_assign_pointer
 + RCU_INIT_POINTER
   (..., NULL)
