Subject: [PATCH] nohz: put proper symbol in the unstable schedclock warning

Since e12d0271 ("nohz: Warn if the machine can not perform nohz_full") 
Kernel triggers a WARN() in case sched clock is marked as unstable.

Make it output a proper Kconfig symbol (NO_HZ_FULL) when informing user 
about this.
