Finish an asynchronous verify chain operation. See
g_tls_database_verify_chain() 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.
