[SCSI] iscsi_tcp: don't fire conn error if pdu init fails
If a command's scsi cmd pdu setup fails then we can just fail the IO to the scsi layer. If a DATA_OUT for a R2T fails then we will want to drop the session, because it means we got a bad request from the target (iscsi protocol error). This patch has us propogate the error upwards so libiscsi_tcp or libiscsi can decide what the best action is to take. It also fixes a bug where we could try to grab the session lock while holding it, because if iscsi_tcp drops the session in the pdu setup callout the session lock is held when setting up the scsi cmd pdu.
