staging: vt6656: s_vFillCTSHead join structures of vnt_cts* to union vnt_tx_data_head
Only one of vnt_rts*/vnt_cts* structures are accessed at any one time.
structures vnt_cts and vnt_cts_fb are members of union vnt_tx_data_head.
Create pointer union head and point structures to the correct member.
Point the union to pvCTS.
