[CRIU] [PATCH 1/2] fix coverity false positive

[Tycho Andersen]

As mentioned in #110 on github, I think coverity's complaint here is
actually a false positive, since there's no way for render_lsm_profile to
return non-zero when rendered == NULL. That said, this should fix the
complaint by the static analyzer.

Closes #110
