X-Git-Tag: v4.4-rc1~158^2~2^2^4~2

rcutorture: Fix unused-function warning for torturing_tasks()

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.
