drivers/staging/vt6656/rxtx.c:729 vnt_beacon_xmit()
warn: struct type mismatch 'vnt_beacon_buffer vs vnt_tx_usb_header'

Since the only part of vnt_beacon_buffer is used remove and
replace it with vnt_tx_usb_header.

Fixes: 9deca1e3e2b6 ("staging: vt6656: vnt_beacon_xmit use extra_tx_headroom.")

It's not really a bug fix.  It's just a cleanup.  But whatever...
