ivshmem: Improve MSI irqfd error handling
Adds a rollback path to ivshmem_enable_irqfd() and fixes ivshmem_disable_irqfd() to bail if irqfd has not been enabled. To reproduce, run: ivshmem-server -n 0 and QEMU with: -device ivshmem-doorbell,chardev=iv -chardev socket,path=/tmp/ivshmem_socket,id=iv then load, unload, and load again the Windows driver, at the time of writing available at: https://github.com/virtio-win/kvm-guest-drivers-windows/tree/master/ivshmem The issue is believed to have been masked by other guest drivers, notably Linux ones, not enabling MSI-X on the device.
