QUIC: prevent deleted stream frame retransmissions.

Browse Source 
Since a2a513b93c, stream frames no longer need to be retransmitted after it
was deleted.  The frames which were retransmitted before, could be stream data
frames sent prior to a RESET_STREAM. Such retransmissions are explicitly
prohibited by RFC 9000, Section 19.4.
