h223: fix warning related to circuit_id in circuit_chain_lookup
Fixes a build failure when building the wireshark-git package on Arch
Linux using GCC 7.2.1:
epan/dissectors/packet-h223.c: In function ‘dissect_mux_sdu_fragment’:
epan/dissectors/packet-h223.c:207:13: error: variable ‘circuit_id’
might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
Fixes: v2.5.0rc0-1698-g800b26edbe ("Remove circuit API")
