Fix backcompat for hotplug of SCSI controllers
SCSI controllers have no trouble existing without any attached disks. This could be achieved with the (legacy) monitor syntax pci_add pci_addr=auto storage if=scsi This is now denied with scsi requires a backing file/device. failed to add if=scsi There is no need for this denial and it breaks compatability with existing QEMU usage, so remove the check for presence of a drive.
