stable inclusion from stable-v5.10.107 commit 3f9a8f8a952c4678594d22b601943ad95c62fa18 bugzilla: https://gitee.com/openeuler/kernel/issues/I574A2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit e50b88c4f076242358b66ddb67482b96947438f2 ]
The wdev channel information is updated post channel switch only for the station mode and not for the other modes. Due to this, the P2P client still points to the old value though it moved to the new channel when the channel change is induced from the P2P GO.
Update the bss channel after CSA channel switch completion for P2P client interface as well.
