Re: [libvirt] [PATCH] lxc_controller.c: don't ignore failed "accept"

coverity complained (rightly) about the risk of closing a negative

for a failed "accept" call. I'm not 100% sure that a failed
accept call deserves to provoke a "goto cleanup", but doing that
is consistent with what the nearby code does upon epoll_ctl failure.
This isn't correct because the incoming client can quit between the
time of poll() indicating its presence, and accept() trying to process
it. This is an expected non-fatal scenario, so it should just be
ignored without quitting. epoll_ctl() by comparison is a fatal system
error, so has to be handled as an unrecoverable error
