wifi: ath12k: Correct 6 GHz frequency value in rx status

The frequency in the rx status is currently being filled
incorrectly for the 6 GHz band. The channel number received is
invalid in this case, resulting in packet drops. Fix this
issue by correcting the frequency calculation.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
