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.
