accel/kvm: Make "kernel_irqchip" default on
Commit 11bc4a13d1f4 ("kvm: convert "-machine kernel_irqchip" to an
accelerator property") moves kernel_irqchip property from "-machine" to
"-accel kvm", but it forgets to set the default value of
kernel_irqchip_allowed and kernel_irqchip_split.
Also cleaning up the three useless members (kernel_irqchip_allowed,
kernel_irqchip_required, kernel_irqchip_split) in struct MachineState.
Fixes: 11bc4a13d1f4 ("kvm: convert "-machine kernel_irqchip" to an accelerator property")
