base-bearer: fix check for cancellation

If we cancel connect_cancellable, the connect task will return a
G_IO_ERROR_CANCELLED. We may need to do some cleanup (like, disconnect
if the connection went far enough to actually start the network
connection), thus it's important we check for cancellation correctly.
