  ovn-sbctl: Prevent core dump from ovn-sbctl lflow-list [datpath] 0xflow

When ovn-sbctl lflow-list gets lflow argument with 0x prefix, e.g. 0x8131c8a8,
it prints correct output, but fails with coredump.
For example:
ovn-sbctl --uuid lflow-list sw1 0x8131c8a8

Datapath: "sw1" (4b1e53d8-9f0f-4768-b4a6-6cbc58a4bfda)  Pipeline: egress
    uuid=0x8131c8a8, table=10(ls_out_port_sec_l2 ), priority=100  ,
match=(eth.mcast), action=(output;)
free(): invalid pointer
[2]    616553 abort (core dumped)  ovn-sbctl --uuid dump-flows sw1 0x8131c8a8

 This patch fixes it.
