x86/hyperv: Fix usage of cpu_online_mask to get valid cpu
Accessing cpu_online_mask here is problematic because the cpus read lock
is not held in this context.
However, cpu_online_mask isn't needed here since the effective affinity
mask is guaranteed to be valid in this callback. So, just use
cpumask_first() to get the cpu instead of ANDing it with cpus_online_mask
unnecessarily.
