gst: sink: post an element error when all buffers are removed abruptly

Browse source 
When the link on the pipewire side is destroyed, on video streams, buffers
are removed abruptly and there is no way this pipeline can be revived,
so let's post an element error to stop it.

On a normal shutdown, the pool is first set to flushing in change_state(),
so checking for the flushing state is a good indicator to know if this
is a normal shutdown or not.

See #1980
