[v2,0/1] COLO: Fix memory leak in packet_enqueue()

Message

The patch is to fix the memory leak in packet_enqueue().
The allocated "pkt" needs to be freed if the colo compare
primary or secondary queue is too big to insert.

Reproduce steps:
(1) Setup PVM and SVM both with NIC e1000 by the steps descripted
    in the wiki qemu/COLO
(2) Run "iperf3 -s" in PVM
(3) Run "iperfs -c <PVM-IP> -t 7200"

The memory usage of qemu-system-x86_64 increases as the PVM's QMP 
shows "qemu-system-x86_64: colo compare secondary queue size too big,
drop packet".

Please review, thanks.

V2:
 - Fix incorrect patch format
