vaapipostproc: fix reference counting buf for passthrough mode.

Browse source 
Fix reference counting bug for passthrough mode, whereby the input buffer
was propagated as is downstream through gst_pad_push() without increasing
its reference count before. The was a problem when gst_pad_push() returns
an error and we further decrease the reference count of the input buffer.
