[PATCH 5/5] staging: vt6656: rxtx.c s_vFillRTSHead/s_vFillCTSHead move union vnt_tx_data_head up one level.

[Malcolm Priestley <tvboxspy@xxxxxxxxx>]

Move
s_vFillRTSHead union vnt_tx_data_head to void *pvRTS argument.
s_vFillCTSHead union vnt_tx_data_head to void *pvCTS argument.

In s_vGenerateTxParameter create union vnt_tx_data_head
pointing to rts_cts;
