wifi: ath12k: report station mode receive rate for IEEE 802.11be

Browse Source 
Currently, the receive rate of EHT of "iw dev xxx station dump" command
always show an invalid value.

This is because ath12k does not pass information about the rx_status of EHT
to mac80211. So, mac80211 not calculate the receive rate.

To address this issue, add logic for handling rx_status of EHT to the
ath12k_dp_rx_h_rate() function.

After that, "iw dev xxx station dump" show the correct receive rate.
Such as:

Station 00:03:7f:12:03:03 (on wlo1)
        inactive time:  48 ms
        rx bytes:       59226
        rx packets:     320
        tx bytes:       26556
        tx packets:     191
        tx retries:     99
        tx failed:      0
        beacon loss:    0
        beacon rx:      79
        rx drop misc:   68
        signal:         -95 dBm
        beacon signal avg:      -20 dBm
        tx bitrate:     688.2 MBit/s 40MHz EHT-MCS 13 EHT-NSS 2 EHT-GI 0
        tx duration:    0 us
        rx bitrate:     619.5 MBit/s 40MHz EHT-MCS 8 EHT-NSS 3 EHT-GI 0

This patch affects the station mode of WCN7850 and QCN9274.
