Subject: [PATCH AUTOSEL 5.17 025/135] rtw88: fix incorrect frequency reported

From: Po-Hao Huang <phhuang@...ltek.com>

[ Upstream commit 6723c0cde84fde582a261c186ce84100dcfa0019 ]

We should only fill in frequency reported by firmware during scan.
Add this so frames won't be dropped by mac80211 due to frequency
mismatch.
