OK, Nic cc'd

    libiscsi, iser: Adjust data_length to include protection information
    
    In case protection information exists over the wire
    iscsi header data length is required to include it.
    Use protection information aware scsi helpers to set
    the correct transfer length.
    
    In order to avoid breakage, remove iser transfer length
    checks for each task as they are not always true and
    somewhat redundant anyway.

Came to go through the target tree even though it's initiator only and
how come it was tagged for stable?
