Subject: instance: exit in case asprintf() fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ad652490d47916a27c01e3dd8f9eafcecbb4bc7f;p=project%2Fprocd.git

instance: exit in case asprintf() fails

If asprintf returns -1 we are most likely out of memory, so just exit
in that case.
