When created, the IOAPIC entries should be masked, as it is the guest's responsibility (FW and/or OS) to unmask them if/when necessary. This patch saves a full round of port I/O writes from the guest to the IOAPIC, meant for masking the unmasked entries. Because they're now masked, the entries are not enabled, which means they are not connected from a KVM perspective, saving from unneeded registration/unregistration of the irq fds.
