The unpacked_lun field in the SCSI target tracepoints should be
initialized with cmd->orig_fe_lun rather than cmd->se_lun->unpacked_lun
for two reasons:
- most importantly, if we are in the cmd_complete tracepoint
returning a check condition due to no LUN found, cmd->se_lun will
be NULL and we'll crash trying to dereference it.
- also, in any case, cmd->se_lun->unpacked_lun is an internal index
into the target's internal set of LUNs; cmd->orig_fe_lun is much
more useful and interesting, since it's the value the initiator
actually sent.
