[Qemu-devel] [PATCH v6 07/29] libqtest: Remove dead qtest_instances variable

[Eric Blake <eblake@redhat.com>]

Prior to commit 063c23d9, we were tracking a list of parallel
qtest objects, in order to safely clean up a SIGABRT handler
only after the last connection quits.  But when we switched to
more of glib's infrastructure, the list became dead code that
is never assigned to.
