Subject: [PATCH 4.8 053/125] ath10k: fix reporting channel survey data

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ashok Raj Nagarajan <arnagara@....qualcomm.com>

commit 77eb3d693182b4eaa88c6ba406fbb92b1f1bd636 upstream.

When user requests for survey dump data, driver is providing wrong survey
information. This information we sent is the survey data that we have
collected during previous user request.

This issue occurs because we request survey dump for wrong channel. With
this change, we correctly display the correct and current survey
information to userspace.
