iSCSI: AMG Last call comments

["Ayman Ghanem" <aghanem@cisco.com>]

I only have two minor technical comments. A few editorials will go to
Julian.

1. Near the end of 9.3.4 (SCSI Command):
   If the Expected Data Transfer Length is higher than the FirstBurst-
   Length (the negotiated maximum amount of unsolicited data the target
   will accept), the initiator MUST send the maximum length of unsolic-
   ited data OR ONLY the immediate data.

suggest adding:
   ..........OR ONLY the immediate data, if any.

2. 9.12 (Login Request)
   Login requests are always considered as immediate.

suggest setting the I-bit in the login PDU to 1 instead of rsvd
