Subject: [PATCH] sysv-generator: properly translate sysv facilities

We used the wrong return value in one case, so that our translations were
thrown away.

While we are at it, make sure to always initialize *ret on successful function
exits.

Fixes: #4762
(cherry picked from commit e932f5407ef5ad05d25d7dfefa4cda0fe81cc346)
