[PATCH v4 2/2] qedit: Do not force the sample to be freed in SampleGrabber_callback().

[Brendan McGrath]

This patch removes a work around that causes a crash in Unravel Two.

There is a callback in Unravel Two that appears to add a reference to a
IMediaSample, which this workaround treats as a leak and releases. However, the
application also later releases the reference itself, causing a use-after-free.
