MINOR: mux-quic: do not trace error in qcc_send_frames() on empty list

qcc_send_frames() can be called with an empty list and returns
immediately with an error code. This is convenience to be able to call
it in a while loop.

Remove the trace with "error" when this is the case and replacing it
with a less alarming "leaving on..." message. This should help debugging
when traces are active.
