gcancellable: Assert that make_pollfd() call succeeds
The `make_pollfd()` call can’t fail because it only does so if `cancellable == NULL`, and we’ve already checked that. Assert that’s the case, to shut Coverity up and to catch behavioural changes in future. Coverity CID: #1159433 Signed-off-by: Philip Withnall <withnall@endlessm.com>
