sched: Fix warning in kernel/sched/fair.c
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.
