[GIT PULL 05/23] net/colo: fix g_hash_table_destroy assertion on uninitialized filter

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

colo_rewriter_cleanup() unconditionally destroys connection_track_table,
but the table is only allocated in colo_rewriter_setup(). When the
filter-rewriter object is finalized without having been set up (e.g.
during qom-test property enumeration), the pointer is NULL and
g_hash_table_destroy() fires an assertion.

Use g_clear_pointer() to skip the destroy when the table was never
initialized.
