Subject: Clean-up: sessiond: ust-app: ua_sess is never populated on failure
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=6d2f8aae34a4e1e219a29db407dd0ea6805b690b;p=lttng-tools.git

Clean-up: sessiond: ust-app: ua_sess is never populated on failure

When find_or_create_ust_app_session() fails, it doesn't populate its
return parameter. Therefore, it is unnecessary to destroy the app
session when it returns < 0.
