syncobj: ensure we only add waiters on succesful checks (#9412)

timeline check only returns nullopt on ETIME_ERR , meaning the if check
later on returns true if drmSyncobjTimelineWait returns anything else
like EINVAL/EPERM/EACCESS etc, so actually check the returned .value()
of the std::optional. also move the fd to rvalue references.
