posix-timers: Replace call_rcu() by kfree_rcu() for simple kmem_cache_free() callback
Since SLOB was removed and since commit 6c6c47b063b5 ("mm, slab: call
kvfree_rcu_barrier() from kmem_cache_destroy()"), it is not longer
necessary to use call_rcu() when the callback only performs
kmem_cache_free(). Use kfree_rcu() directly.
The changes were made using Coccinelle.
