scsi: target: Fix LUN ref count handling
Fix two bugs in the LUN refcounting:
1. For the TCM_WRITE_PROTECTED case we were returning an error after
taking a ref to the LUN, but never dropping it (caller just send status
and drops cmd ref).
2. We still need to do a percpu_ref_tryget_live for the virt LUN 0 like we
do for other LUNs, because the TPG code does the refcount/wait process
like it does with other LUNs.
