[iSCSI] CmdSN for Text Command

["Lakshmi Ramasubramanian" <nramas@windows.microsoft.com>]

Section 10.10.4 Target Transfer Tag (Text Request)
says that if F bit is set to 0 in Text Response, initiator
must send an empty text command so that the target can
send the next text response. Should the initiator use
the original CmdSN when it sends the empty text command
or should it use the next CmdSN (Assuming Immediate Bit
is NOT set in any of the Text Command PDUs)?

Thanks!
