staging: vt6655: use ieee80211_tx_info to select packet type.

commit a6388e68 upstream.

Information for packet type is in ieee80211_tx_info

band IEEE80211_BAND_5GHZ for PK_TYPE_11A.

IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB

This ensures that the packet is always the right type.
