This patch adds a explicit check in iscsit_find_cmd_from_itt_or_dump() to ignore commands with ICF_GOT_LAST_DATAOUT set. This is done to address the case where an ITT is being reused for DataOUT, but the previous command with the same ITT has not yet been acknowledged by ExpStatSN and removed from the per connection command list. This issue was originally manifesting itself by referencing the previous command during ITT lookup, and subsequently hitting the check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that resulted in the DataOUT PDU + associated payload being silently dumped.
