Víctor Manuel Jáquez Leal 14c28415b9 va: Remove gst_va_decoder_destroy_buffers() 
Since GstVaDecodePicture is destroyed completely with its free() function and
it's used as destroy notify by codecs picture, there's no need to call
gst_va_decoder_destroy_buffers() externally, since the codecs base classes
destroy the codec picture when it's required.

/**
* SECTION:element-vah265dec
* @title: vah265dec
* @short_description: A VA-API based H265 video decoder
*
* vah265dec decodes H265 bitstreams to VA surfaces using the
* installed and chosen [VA-API](https://01.org/linuxmedia/vaapi)
* driver.
*
* The decoding surfaces can be mapped onto main memory as video
* frames.
*
* ## Example launch line
* ```
* gst-launch-1.0 filesrc location=big_buck_bunny.mov ! parsebin ! vah265dec ! autovideosink
* ```
*
* Since: 1.20
*

/* ToDo:
*
* + interlaced streams
* + mutiview and stereo profiles
* + SCC extension buffer
* + Add 10bit support
