From: Peter Oh <peter.oh@xxxxxxxxxxxxxxxxx> Mesh interface has used its channel parameters that configured during its initialization even after channel switched due to DFS radar detection during CAC which caused channel switch error. This change fixes the error by updating its channel parameters when channel's been changed from initial one.
