Bluetooth: Fix accepting set_dev_class for non-BR/EDR controllers

Browse Source 
The concept of Class of Device only exists for BR/EDR controllers. The
mgmt_set_dev_class command should therefore return a proper "not
supported" error if it is attempted for a controller that doesn't
support BR/EDR (e.g. a single mode LE-only one).
