wifi: mac80211: fix missing RX bitrate update for mesh forwarding path

Browse Source 
Currently, RX bitrate statistics are not updated for packets received
on the mesh forwarding path during fast RX processing. This results in
incomplete RX rate tracking in station dump outputs for mesh scenarios.

Update ieee80211_invoke_fast_rx() to record the RX rate using
sta_stats_encode_rate() and store it in the last_rate field of
ieee80211_sta_rx_stats when RX_QUEUED is returned from
ieee80211_rx_mesh_data(). This ensures that RX bitrate is properly
accounted for in both RSS and non-RSS paths.
