a4c96ae319 "sched: Unthrottle rt runqueues in __disable_runtime()"
turned the unthrottle_offline_cfs_rqs function into a static symbol,
which now triggers a warning about it being potentially unused:
kernel/sched/fair.c:2055:13: warning: 'unthrottle_offline_cfs_rqs' defined but
not used [-Wunused-function]
Marking it __maybe_unused shuts up the gcc warning and lets the
compiler safely drop the function body when it's not being used.
To reproduce, build the ARM bcm2835_defconfig.
