rtc_status is used to track RTC interrupt delivery status. The pending_eoi will be increased by vcpu who received RTC interrupt and will be decreased when EOI to this interrupt. Also, we use dest_map to record the destination vcpu to avoid the case that vcpu who didn't get the RTC interupt, but issued EOI with same vector of RTC and descreased pending_eoi by mistake.
