Andy Grover 5a7125c64d target/pscsi: Don't leak scsi_host if hba is VIRTUAL_HOST
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.
