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: âtick_broadcast_oneshot_offlineâ \
	  declared âstaticâ 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")
