1. Discovery session nil handler crash: reject SCSI commands with
Reject PDU when s.scsi is nil (discovery sessions have no target).
2. CmdSN window enforcement: validate incoming CmdSN against
[ExpCmdSN, MaxCmdSN] using serial arithmetic. Drop out-of-window
commands per RFC 7143 section 4.2.2.1.
3. Data-Out buffer offset validation: enforce BufferOffset == received
for ordered data (DataPDUInOrder=Yes). Prevents silent corruption
from out-of-order or overlapping data.
4. ImmediateData enforcement: reject immediate data in SCSI command
PDU when negotiated ImmediateData=No.
5. UNMAP descriptor length alignment: reject blockDescLen not a
multiple of 16 bytes.
