x86: kvmclock: remove check_and_clear_guest_paused warning
CPU offline path calls the hrtimer interrupt handler with interrupts disabled, without touching preempt_count, triggering this warning. Remove the warning since it is supposed to be used from hrtimer interrupt context only. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
