[SCSI] scsi_host regression: fix scsi host leak

scsi: use class iteration api
Isn't a correct replacement for the original hand rolled host
lookup. The problem is that class_find_child would get a reference to
the host's class device which is never released. Since the host class
device holds a reference to the host gendev, the host can never be
freed.
In 2.6.26 we started using class_find_device, and this function also
gets a reference to the device, so we end up with an extra ref
and the host will not get released.
This patch adds a put_device to balance the class_find_device() get. I
kept the scsi_host_get in scsi_host_lookup, because the target layer
is using scsi_host_lookup and it looks like it needs the SHOST_DEL
check.
