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.
