[PATCH tip/core/rcu 6/6] rcutorture: Fix rcu_torture_cbflood() memory leak

[Paul E. McKenney]

From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>

Commit 38706bc5a29a (rcutorture: Add callback-flood test) vmalloc()ed
a bunch of RCU callbacks, but failed to free them.  This commit fixes
that oversight.
