When station mode don't disconnect when we get channel switch from AP to DFS channel. Most/all APs send CSA request after pass background CAC. In other case we should disconnect after detect beacon miss. Without patch when we get CSA to DFS channel get: "kernel: wlo1: preparing for channel switch failed, disconnecting" Signed-off-by: Janusz Dziedzic <janusz.dziedzic@gmail.com>

Seems today only mt7921 in my laptop behave like this (disconnect each CSA to DFS channel). Don't see this when using Intel or Qualcomm wifi card in station mode.
