[PATCH] ath11k: remove return for empty tx bitrate in mac_op_sta_statistics

[Wen Gong <wgong@xxxxxxxxxxxxxx>]

Currently in ath11k_mac_op_sta_statistics() there is the following
logic:
    if (!arsta->txrate.legacy && !arsta->txrate.nss)
        return;

Unfortunately if this condition is true then the function returns
without setting parameters that follow the txrate.

To address this issue remove the return and instead invert the logic
to set the txrate logic if (arsta->txrate.legacy || arsta->txrate.nss).

Same change which is upstream also exists in ath10k:
1cd6ba8ae33e ("ath10k: remove return for NL80211_STA_INFO_TX_BITRATE")

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
