[PATCH] KVM: Merge kvm_ioapic_get_delivery_bitmask into kvm_get_intr_delivery_bitmask

Gleb fixed bitmap ops usage in kvm_ioapic_get_delivery_bitmask. Sheng merged two functions, as well as fix several issues in kvm_get_intr_delivery_bitmask: 1. deliver_bitmask is a bitmap rather than a unsigned long intereger. 2. Lowest priority target bitmap wrong calculated by mistake. 3.
