platform/x86: wmi: Decouple legacy WMI notify handlers from wmi_block_list
Until now, legacy WMI notify handler functions where using the
wmi_block_list, which did no refcounting on the returned WMI device.
This meant that the WMI device could disappear at any moment,
potentially leading to various errors.
Fix this by using bus_find_device() which returns an actual
reference to the found WMI device.
Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.
