Subject: Fix minor memory leaks found by valgrind.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e49190c4933bdb4219c7fe5fb84768a076a1ff75;p=openvswitch

Fix minor memory leaks found by valgrind.

All of these leaks are in normally short-lived programs, so none of them
is very important.
