[SCSI] libiscsi: fix potential buffer overrun in __iscsi_conn_send_pdu
This patches fixes a potential buffer overrun in __iscsi_conn_send_pdu. This function is used by iscsi drivers and userspace to send iscsi PDUs/ commands. For login commands, we have a set buffer size. For all other commands we do not support data buffers.
