ath11k: fix packet drops due to incorrect 6 GHz freq value in rx status

Browse Source 
[ Upstream commit 9d6ae1f5cf733c0e8d7f904c501fd015c4b9f0f4 ]

Frequency in rx status is being filled incorrectly in the 6 GHz band as
channel number received is invalid in this case which is causing packet
drops. So fix that.

Fixes: 5dcf42f8b79d ("ath11k: Use freq instead of channel number in rx path")
