MINOR: quic: Probe even if coalescing

Browse Source 
Again, we fix a reminiscence of the way we probed before probing by packet.
When we were probing by datagram we inspected <prv_pkt> to know if we were
coalescing several packets. There is no need to do that at all when probing by packet.
Furthermore this could lead to blocking situations where we want to probe but
are limited by the congestion control (<cwnd> path variable). This must not be
the case. When probing we must do it regardless of the congestion control.
