[libvirt] [PATCH] daemon: Plug memory leaks

[Alex Jia]

Detected by valgrind. Leaks are introduced in commit 6e6e9be.

* daemon/libvirtd-config.c (macro GET_CONF_STR): fix memory leaks.

How to reproduce?

% make && make -C tests check TESTS=libvirtdconftest
% cd tests && valgrind -v --leak-check=full ./libvirtdconftest

actual result:

==11008== 185 bytes in 5 blocks are definitely lost in loss record 3 of 5
