nimble/ll: Fix data length update from host

Browse Source 
When host updates suggested data length we should also update values for
coded and uncoded PHYs since these values will be used when connection
is initialized. Otherwise we will basically disregard host suggestion
when PHY support is enabled (which we can do, but we do not want to).
