When retiring QEMU_CAPS_BLOCKDEV_HOSTDEV_SCSI capability the commit removed a bit too much. Previously, all other devices than VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI were ignored in qemuDomainDeviceHostdevDefPostParseRestoreBackendAlias(). But the commit in question removed not only the capability check but also this return early statement. Restore it back.
