Subject: posix-timers: Unbreak CONFIG_POSIX_TIMERS=n build
Patch-mainline: v5.4-rc1
Git-commit: 8f2edb4a78f7f5fa35c025849152b1d2dfaee4eb
References: bsc#1162702

The rework of the posix-cpu-timers patch series dropped the empty
declaration of struct cpu_timer for the CONFIG_POSIX_TIMERS=n case which
causes the build to fail:

./include/linux/posix-timers.h:218:20: error: field 'cpu' has incomplete type

Add it back.

Fixes: 60bda037f1dd ("posix-cpu-timers: Utilize timerqueue for storage")
