qemu: support persistent hotplug of <hostdev> devices

Browse Source 
For some reason, although live hotplug of <hostdev> devices is
supported, persistent hotplug is not. This patch adds the proper
VIR_DOMAIN_DEVICE_HOSTDEV cases to the switches in
qemuDomainAttachDeviceConfig and qemuDomainDetachDeviceConfig.
