KVM: use proper hrtimer function to retrieve expiration time
hrtimer->base can be temporarily NULL due to racing hrtimer_start. See switch_hrtimer_base/lock_hrtimer_base. Use hrtimer_get_remaining which is robust against it. CC: stable@kernel.org Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
