MINOR: quic: Replace quic_tx_frm struct by quic_frame struct

These structures are similar. quic_tx_frm was there to try to reduce the
size of such objects which embed a union for all the QUIC frames.
Furtheremore this patch fixes the issue where quic_tx_frm objects were freed
from the pool for quic_frame.
