clocksource: replace cpumask_weight with cpumask_empty in clocksource.c
clocksource_verify_percpu() calls cpumask_weight() to check if any bit of
a given cpumask is set. We can do it more efficiently with cpumask_empty()
because cpumask_empty() stops traversing the cpumask as soon as it finds
first set bit, while cpumask_weight() counts all bits unconditionally.
