[PATCH 4/4] qemu: hostdev: Introduce qemuUpdateActiveHostDevices()

[Andrea Bolognani <abologna@xxxxxxxxxx>]

This calls the PCI-, USB- and SCSI-specific functions just like
qemuPrepareHostDevices() and qemuDomainReAttachHostDevices()
already do.

Update qemuProcessReconnect() to use the new function.
