3.13.11-ckt23 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Andy Grover <agro...@redhat.com> commit 5a7125c64def3b21f8147eca8b54949a60963942 upstream. See https://bugzilla.redhat.com/show_bug.cgi?id=1025672 We need to put() the reference to the scsi host that we got in pscsi_configure_device(). In VIRTUAL_HOST mode it is associated with the dev_virt, not the hba_virt.
