Another one liner. If no rules were passed to
sdap_sudo_rules_refresh_send (if rules[0] was NULL) and no error
occurred, then variable ret was used uninitialized. This is not very
likely to happen, but it is safer to have it initialized.
Maybe we should consider adding initialization of all "ret" variables to
our coding guidelines to avoid these "unlikely but possible" errors in
new code.
Patch attached.
