scsi: iscsi: Fix HW conn removal use after free
If qla4xxx doesn't remove the connection before the session, the iSCSI
class tries to remove the connection for it. We were doing a
iscsi_put_conn() in the iter function which is not needed and will result
in a use after free because iscsi_remove_conn() will free the connection.
