Change the density value to be constrained by config_maxUIWidth, in case of user switch

When user switches, density is reset to forcedDensity for that user. If
there is no forcedDensity value for the user, the density is reset to
initial density value. This initial density is not constarined by
config_maxUIWidth, which cause UX issue in devices with
config_maxUIWidth.
