iscsi: Use 0 instead of SPDK_SUCCESS in spdk_iscsi_read_pdu to match caller

spdk_iscsi_read_pdu has been used only in a place,
iscsi_conn_handle_incoming_pdus. iscsi_conn_handle_incoming_pdus
classifies return code of spdk_iscsi_read_pdu to
SPDK_ISCSI_CONNECTION_FATAL, 0, or 1.

Using 0 instead of SPDK_SUCCESS in spdk_iscsi_read_pdu matches
iscsi_conn_handle_incoming_pdus and is done in this patch.
