6574158ae6 l2cap-ertm: try to negotiate 'No FCS' in order to work around iOS bug 
Issue: iOS (e.g. 10.2) uses 'No FCS' as default while Core 5.0 specifies 'FCS' as default
Workaround: try to actively negotiate 'No FCS' and fall back to 'FCS' if 'No FCS' is rejected
This works as iOS accepts the 'No FCS' request, hence the default value is only used on non-iOS devices
