In configurations with CONFIG_TICK_ONESHOT but no CONFIG_NO_HZ or
CONFIG_HIGH_RES_TIMERS, tick_sched_timer_dying() is stubbed out,
but still defined as a global function as well:

kernel/time/tick-sched.c:1599:6: error: redefinition of 'tick_sched_timer_dying'
 1599 | void tick_sched_timer_dying(int cpu)
      |      ^
kernel/time/tick-sched.h:111:20: note: previous definition is here
  111 | static inline void tick_sched_timer_dying(int cpu) { }
      |                    ^

This configuration only appears with ARM CONFIG_ARCH_BCM_MOBILE,
which should not actually select CONFIG_TICK_ONESHOT.

Adjust the #ifdef for the stub to match the condition for building the
tick-sched.c file for consistency with the definition and to avoid
the build regression.

Fixes: 3aedb7fcd88a ("tick/sched: Remove useless oneshot ifdeffery")
