hrtimer: remove warning in hres_timers_resume
hres_timers_resume() warns if there appears to be more than one cpu
online. This warning makes sense when the suspend/resume mechanism
offlines all cpus but one during the suspend/resume process.
However, Xen suspend does not need to offline the other cpus; it
merely keeps them tied up in stop_machine() while the virtual machine
is suspended. The warning hres_timers_resume issues is therefore
spurious.
