wdc: Fix UUID index fallback mechanism

For certain devices that don't support UUID lists, there may be multiple
definitions of the C2 logpage. This code will check for UUID list
support and search the UUID list for the correct UUID, if supported. If
UUID lists are not supported, the code will try uuid index 0 and 1 and
use an identification algorithm to determine which is returning the
correct log page data.
