[Devendra Naga]

valgrind reported the following leak on fc18 system:

valgrind -v --leak-check=full --track-fds=yes ./brctl show

==27307==
==27307== FILE DESCRIPTORS: 4 open at exit.
==27307== Open AF_UNIX socket 3: <unknown>
==27307==    at 0x397B2F3617: socket (in /usr/lib64/libc-2.16.so)
==27307==    by 0x403CF7: br_init (libbridge_init.c:35)
==27307==    by 0x4010BF: main (brctl.c:63)

fix it by calling br_shutdown
