A bunch of fixes and reworks for s390x/pci hotplug infrastructure.

Patch 1,2: Reworks already posted (pre_plug handler)
Patch 3,4: Fixes for memory leaks
Patch 5: Rework unplug handler (introduce unplug_request handler) which
         also fixes some unplug scenarios
Patch 6: RFC patch regarding handling leftover unplug requests on reboot

We might decide to drop 1. 3 and 4 can be picked up independently.

David Hildenbrand (6):
  s390x/pci: Use hotplug_dev instead of looking up the host bridge
  s390x/pci: Move some hotplug checks to the pre_plug handler
  s390x/pci: Always delete and free the release_timer
  s390x/pci: Ignore the unplug call if we already have a release_timer
  s390x/pci: Introduce unplug requests and split unplug handler
  s390x/pci: unplug remaining devices on pcihost reset
