b43: fix b43_plcp_get_bitrate_idx_ofdm return type

Browse Source 
This patch fixes the return type of b43_plcp_get_bitrate_idx_ofdm. If
the plcp contains an error, the function return value is 255 instead
of -1, and the packet was not dropped. This causes a warning in
__ieee80211_rx function because rate idx is out of range.
