media: don't keep last sample reference on sinks
Holding a reference to a GstBuffer somewhere in a pipeline for possibly
indefinite period may cause trouble when the buffer has been allocated
by a 3rd party library or when it points directly into memory region of
a hardware device.
A specific example is V4L2 source element, which won't allow webcam
image resolution be reconfigured unless all previously allocated buffers
have been freed.
Backport of Pidgin 3 commit 13807c514810.
