platform/x86: dell-ddv: Fix taking the psy->extensions_sem lock twice
Calling power_supply_get_property() inside dell_wmi_ddv_battery_translate() can cause a deadlock since this function is also being called from the power supply extension code, in which case psy->extensions_sem is already being held. Fix this by using the new power_supply_get_property_direct() function to ignore any power supply extensions when retrieving the battery serial number. Tested on a Dell Inspiron 3505.
