wifi: ath12k: pack HTT pdev rate stats structs

[ Upstream commit fee9b1f6691120182136edacf590f52d62d9de7f ]

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