staging: vt6655: replace -typedef struct tagSTxDataHead_a_FB with struct vnt_tx_datahead_a_fb

Replace members
a, wDuration, wTimeStampOff, wDuration_f0, and wDuration_f1;
with
a, duration, time_stamp_off, duration_f0, duration_f1

All unsigned short members should be  __le16

Creating the new structure in rxtx.h.
