SAP sets up on 5180/20Mhz, freq 5180 becomes unsafe, channel
switch from 5180/20Mhz to 5200/20Mhz. Then STA connects to
5180, channel switch from 5200/20Mhz to 5180/80Mhz because of
CONCURRENT_STA_CHANGED_CHANNEL. Then STA is disconnect and
causes channel witch from 5180/80Mhz to 5200/80Mhz. This overlaps
the unsafe channel.
To resovle this issue, check the unsafe channels when csa reason
is unsafe channel.
