Shuhei Matsumoto eb739d0364 iscsi: Fix the case that incoming data is split between data segment and data digest ... When data segment size is 64KB and data digest is enabled, if data segment and data digest are split into different two packets, - pdu->mobj[0] became full first when reading data semgment, - pdu->mobj[1] was allocated but unused and data digest was read. In this case, two SCSI write tasks were submitted by mistake and the second SCSI write task had no data. Fix the bug in this patch. When iscsi_pdu_payload_read() is called and pdu->mobj[0] is full, allocate pdu->mobj[1] only if any of data segment remains to read.
