wifi: ath12k: Fix the QoS control field offset to build QoS header
Currently, in the mac80211 layer, received EAPOL packets are dropped
when the HT control field is present in the QoS header. This issue
arises due to an incorrect QoS control field offset used to build
the QoS header in the MSDU data, leading to a corrupted header in the
mac80211 layer. This issue also applies to other frames that contain
the QoS control field, such as QoS data or Null frames. To resolve
this, use ieee80211_get_qos_ctl() to obtain the correct QoS control
offset from the MSDU data. Additionally, ensure the QoS control header
is copied in little-endian format within the MSDU data.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
