rcu: Don't return a value from rcu_assign_pointer()
Quoting Paul [1]:
"Given that a quick (and perhaps error-prone) search of the uses
of rcu_assign_pointer() in v5.1 didn't find a single use of the
return value, let's please instead change the documentation and
implementation to eliminate the return value."
