kvm: set gsi_bits and max_gsi correctly
The current kvm_init_irq_routing() doesn't set up the used_gsi_bitmap
correctly, and as a consequence pins max_gsi to 32 when it really
should be 1024. I ran into this limitation while testing pci
passthrough, where I consistently got an -ENOSPC return from
kvm_get_irq_route_gsi() called from assigned_dev_update_msix_mmio().
