iscsi-target: Disable Immediate + Unsolicited Data with ISER Protection
This patch explicitly disables Immediate + Unsolicited Data for ISER
connections during login in iscsi_login_zero_tsih_s2() when protection
has been enabled for the session by the underlying hardware.
This is currently required because protection / signature memory regions
(MRs) expect T10 PI to occur on RDMA READs + RDMA WRITEs transfers, and
not on a immediate data payload associated with ISCSI_OP_SCSI_CMD, or
unsolicited data-out associated with a ISCSI_OP_SCSI_DATA_OUT.
v2 changes:
- Add TARGET_PROT_DOUT_INSERT check (Sagi)
- Add pr_debug noisemaker (Sagi)
- Add goto to avoid early return from MRDSL check (nab)
