From: Pranith Kumar <bobby.prani@gmail.com>
This commit removes a stale comment in rcu/tree.c which was left out when some code was moved around previously in commit 2036d94a7b61 ("rcu: Rework detection of use of RCU by offline CPUs") For reference, the following updated comment exists a few lines below this which means the same:
/* Remove the outgoing CPU from the masks in the rcu_node hierarchy. */
