Subject: [PATCH] cgroup: Use RCU_INIT_POINTER(x, NULL) in cgroup.c

This patch replaces rcu_assign_pointer(x, NULL) with
RCU_INIT_POINTER(x, NULL)

The rcu_assign_pointer() ensures that the initialization of a
structure is carried out before storing a pointer to that structure.
And in the case of the NULL pointer, there is no structure to
initialize.  So, rcu_assign_pointer(p, NULL) can be safely converted
to RCU_INIT_POINTER(p, NULL)
