Yury Norov 3a5ff1f6dd x86: Replace cpumask_weight() with cpumask_empty() where appropriate
In some cases, x86 code 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.
