[FFmpeg-cvslog] vaapi_encode: Add an assert in vaapi_encode_truncate_gop()

[Haihao Xiang]

ffmpeg | branch: master | Haihao Xiang <haihao.xiang at intel.com> | Thu May 10 11:08:22 2018 +0800| [7e78801fa5802dd49712d2b1fdb8bb31d8373ecc] | committer: Mark Thompson

vaapi_encode: Add an assert in vaapi_encode_truncate_gop()

The flag of input_available must be set when pic_start is not NULL, so
add an assert to ensure it is true. In addition, the assert on last_pic
is unnecessary now, so remove this assert.
