omxil: Release picture in direct rendering mode.

In direct rendering mode a picture reference is acquired from the video output
module. This reference has to be released when the internal omx buffer which
uses this reference is freed. This avoids a blocking condition where the video
output would wait for a picture to be freed forever.
