Remove spurious error log message

In change id Ie2f306bce6aec697ae584da3f55b3cf72edaa07b, a
shared memory leak was fixed using a workaround that
maintained compatibility with the frozen DRM HAL API
1.1. Unfortunately it triggered an error log message that
was no longer an error condition.  This change just removes
the log line to avoid raising undue concerns.
