[SCSI] qla4xxx: do not reuse session when connecting to different target port
qla4xxx does not check the I_T nexus values correctly so it ends up creating one session to the target. If a portal should disappear or they should be reported in different order the driver will think it is already logged in when it could now be speaking to a different target portal or accessing it through a different initiator port (iscsi initiator port is not tied to hardware and is just the initiator name plus isid so you could end up with multiple ports through one host). This patch has the driver check the iscsi scsi port values when matching sessions (we do not check the initiator name because that is static). It results in a portal from each target portal group getting logged into instead of just one per target. In the future the firmware should hopefully send us notification of other sessions that are created to other portals within the same tpgt and the sessions should have different isids.
