Releases a resources previously allocated by g_cancellable_get_fd()
or g_cancellable_make_pollfd().
For compatibility reasons with older releases, calling this function
is not strictly required, the resources will be automatically freed
when the cancellable is finalized. However, the cancellable will
block scarce file descriptors until it is finalized if this function
is not called. This can cause the application to run out of file
descriptors when many GCancellables are used at the same time.
Since 2.22
