elput: check for a special return valuedevs/bu5hm4n/dnd-fixes

sd_pid_get_session returns ENODATA or ENXIO if it was unable to fetch
the session data for the given pid, reason for that is mostly that the
pid is not running is a session. Adding this as the error value can help
the user debugging the problem without the need of gdb´ing into the
function and checking the return value.
