Pushes a buffer to the peer of pad.
This function will call installed block probes before triggering any
installed data probes.
The function proceeds calling gst_pad_chain() on the peer pad and returns
the value from that function. If pad has no peer, GST_FLOW_NOT_LINKED will
be returned.
In all cases, success or failure, the caller loses its reference to buffer
after calling this function.
