[PATCH 2/5] bridge_driver: Use g_autoptr() for virMacMap

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Let's annotate virMacMap variables in bridge_driver.c with
g_autoptr() so that they are automatically freed upon error. This
may look like a needless commit, since there's no memory leak
currently, but it simplifies the next commit.
