tick/broadcast: Fix warning about undefined tick_broadcast_oneshot_offline()
Randconfig builds with
CONFIG_TICK_ONESHOT=y
CONFIG_HOTPLUG_CPU=n
trigger
kernel/time/tick-broadcast.c:39:13: warning: ‘tick_broadcast_oneshot_offline’ \
declared ‘static’ but never defined [-Wunused-function]
due to that function's definition missing.
Move the CONFIG_HOTPLUG_CPU ifdeffery around its declaration too.
Fixes: 1b72d4323798 ("tick: Remove outgoing CPU from broadcast masks")
