[PATCH tip/core/rcu 04/10] rcuperf: Stop abusing IS_ENABLED()

["Paul E. McKenney" <paulmck@linux.ibm.com>]

The ever-evolving IS_ENABLED() macro is intended for CONFIG_* Kconfig
options, but rcuperf currently uses it for the decidedly non-CONFIG_*
MODULE macro.  In the spirit of not inviting trouble, this commit
substitutes tried-and-true #ifdef.
