In LTE coex SAP restart scenario, currently SAP new channel is selected
base on 20M bandwidth, and channel bandwidth is determined after
channel frequency determined, if new channel bandwidth is greater than
20M, it is possible channel boundary fall in unsafe channel range,
because bonded channel is fixed with different bandwidth.
If select new primary channel with determined bandwidth, it would
violate MCC to SCC limitation if concurrency, to make it simple,
just shrink SAP bandwidth to 20M if check unsafe channel failed.
