BUG/MINOR: quic: Missing initializations for ducplicated frames.

When duplication frames in qc_dup_pkt_frms(), ->pkt member was not correctly
initialized (copied from the original frame). This could not have any impact
because this member is initialized whe the frame is added to a packet.
This was also the case for ->flags.
Also replace the pool_zalloc() call by a call to pool_alloc().

Must be backported to 2.6.
