Yury Norov 911488de05 genirq/affinity: Replace cpumask_weight() with cpumask_empty() where appropriate
__irq_build_affinity_masks() calls cpumask_weight() to check if any bit of
a given cpumask is set.

This can be done 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.
