This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)
Since rcu_assign_pointer() is to ensure that the initialization of a structure
is carried out before storing a pointer to that structure. So,
rcu_assign_pointer(p, NULL)
can be safely converted to RCU_INIT_POINTER(p, NULL).
