target/pscsi: Fix NULL pointer dereference in get_device_type

[ Upstream commit 215a8fe4198f607f34ecdbc9969dae783d8b5a61 ]

This patch fixes a NULL pointer dereference OOPs with pSCSI backends
within target_core_stat.c code.  The bug is caused by a configfs attr
read if no pscsi_dev_virt->pdv_sd has been configured.
