Subject: [PATCH 3/3] ath11k: fix survey dump collection in 6 GHz

From: Pradeep Kumar Chitrapu <[email protected]>

When ath11k receives survey request, choose the 6 GHz band when enabled.
Without this, survey request does not include any 6 GHz band results,
thereby causing auto channel selection to fail.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01386-QCAHKSWPL_SILICONZ-1
