[PATCH 12/38] tick-common: call tick_check_percpu() from tick_check_preferred()

[Viresh Kumar]

tick_check_percpu() and tick_check_preferred() are called from two places and in
exactly same order. So, would make sense to call tick_check_percpu() from
tick_check_preferred() instead, so that their common caller can just call
tick_check_preferred().
