Finish an asynchronous verify chain operation. See
TlsDatabase.verifyChain for more information.
If chain is found to be valid, then the return value will be 0. If
chain is found to be invalid, then the return value will indicate
the problems found. If the function is unable to determine whether
chain is valid or not (eg, because cancellable is triggered
before it completes) then the return value will be
G_TLS_CERTIFICATE_GENERIC_ERROR and error will be set
accordingly. error is not set when chain is successfully analyzed
but found to be invalid.
