platform/x86: dell-wmi: Fix driver interface version query
When I converted dell-wmi to the new bus infrastructure, I left the
call to dell_wmi_check_descriptor_buffer() in dell_wmi_init(). This
could cause two problems:
- An error message when loading the driver on a system without
dell-wmi. We'd try to read the event descriptor even if the WMI
GUID wasn't there.
- A possible race if dell-wmi was loaded manually before wmi was
fully initialized.
Fix it by moving the call to the probe function where it belongs.
