[PATCH tip/core/rcu 2/4] rcutorture: Fix unused-function warning for torturing_tasks()

[Paul E. McKenney]

The torturing_tasks() function is used only in kernels built with
CONFIG_PROVE_RCU=y, so the second definition can result in unused-function
compiler warnings.  This commit adds __maybe_unused to suppress these
warnings.
