We shoud not always return SPDK_ISCSI_CONNECTION_FATAL
in spdk_iscsi_read_pdu function.
Reason: In iscsi_conn_handle_incoming_pdus, the loop
directly return only rc==SPDK_ISCSI_CONNECTION_FATAL.
But it masks all the necessary information. So we would like
to keep some information of the return value for spdk_iscsi_read_pdu,
and we can use error log to track those information.
Then we can return SPDK_ISCSI_CONNECTION_FATAL as the error
return value for iscsi_conn_handle_incoming_pdus function.
