[Qemu-devel] [PATCH v1] s390x/pci: Send correct event on hotplug.

[David Hildenbrand <david@redhat.com>]

Comit 2c28c490571f ("s390x/pci: let pci devices start in configured mode")
changed the initial state of zPCI devices from ZPCI_FS_STANDBY to
ZPCI_FS_DISABLED (a.k.a. configured). However we still only send a
HP_EVENT_RESERVED_TO_STANDBY event to the guest, indicating a wrong
state.

Let's send a HP_EVENT_TO_CONFIGURED event instead, to match the actual
state the device is in.

This fixes hotplugged devices having to be enabled explicitly in the
guest e.g. via echo 1 > /sys/bus/pci/slots/00000000/power.
