rcu: Remove redundant check for rcu_head misalignment
There is now an unconditional check for rcu_head misalignment in __call_rcu(), so remove the old conditional one in debug_rcu_head_queue(). Reported-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
