[PATCH 3/5] util: virSecretLookupParseSecret refactor

[Kirill Shchetiniuk via Devel <devel@xxxxxxxxxxxxxxxxx>]

From: Kirill Shchetiniuk <kshcheti@xxxxxxxxxx>

Refactored the virSecretLookupParseSecret fucntion to use the
virXMLPropUUID fucntion, avoid getting the string and parsing it
later. Previously two separate error states merged into one by using
boolean NXOR operation.
