MINOR: quic: Add traces to debug frames handling during retransmissions

Browse Source 
This is really boring to not know why some retransmissions could not be done
from qc_prep_hpkts() which allocates frames, prepare packets and send them.
Especially to not know about if frames are not remaining allocated and
attached to list on the stack. This patch already helped in diagnosing
such an issue during "-dMfail" tests.
