Subject: [PATCH] Ignore the private VP9 status buffer

Without a flag, user doesn't know VACodedBufferSegment.next pointing
to a private segment status, so we have to ignore this private
status buffer. Otherwise it will result in segmentation fault if user
takes VACodedBufferSegment.next as a VACodedBufferSegment pointer

Example:
gst-launch-1.0 videotestsrc !
video/x-raw,format=NV12,width=3840,height=2160 ! vaapivp9enc !
matroskamux ! filesink location=output.vp9
