Peter Lieven 2f9fda19d2 SOCKET do not queue PDUs with itt==0xffffffff head of queue ...

Queing packets with itt = 0xffffffff (e.g. NOP-Out replies) ahead
of queue because they might have a higher CmdSN than following
packets. This again could lead to a deadlock AND its a protocol
violotion:

RFC3720 Section 3.2.2.1 second last paragraph on Page 21:
"On any connection, the iSCSI initiator MUST send the commands in
increasing order of CmdSN, except for commands that are retransmitted
due to digest error recovery and connection recovery."
