Bug fixes for 3.15

Hi Mauro,

A bunch of fixes for the davinci driver (found with the new vb2 instrumentation and kmemleak) and a vb2 fix: the finish memop wasn't called for prepared or queued buffers. Found with v4l2-compliance and the vb2 instrumentation.

This happens in the corner case where you call QBUF and/or PREPARE_BUF without ever calling STREAMON, and then the vb2 queue is canceled either by calling REQBUFS or closing the filehandle.

Regards,

Hans
