Starts an asynchronous eject on a mountable.
When this operation has completed, callback will be called with user_user data, and the operation can be
finalized with eject_mountable_with_operation.end.
If cancellable is not null, then the operation can be cancelled by triggering
the cancellable object from another thread. If the operation was cancelled, the error
g_io_error_cancelled will be returned.
