Revert "checkpatch: Error out if deprecated RCU API used" 



The definition for single-argument kfree_rcu() has been removed,
so that any further attempt to use it will result in a build error.
Because of this build error, there is no longer any need for a special
check in checkpatch.pl.

Therefore, revert commit 1eacac32.
