wifi: ath12k: pack HTT pdev rate stats structs

In order to ensure the HTT DebugFS structs shared with firmware have
matching alignment, the structs should be packed. Most of the structs
are correctly packed, however the following are not:

ath12k_htt_tx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_ext_stats_tlv

So pack those structs.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Fixes: ba42b22aa336 ("wifi: ath12k: Dump PDEV transmit rate HTT stats")
Fixes: a24cd7583003 ("wifi: ath12k: Dump PDEV receive rate HTT stats")
Fixes: 7a3e8eec8d18 ("wifi: ath12k: Dump additional PDEV receive rate HTT stats")
