Zhao Zhili 066368e837 avcodec/libdavs2: workaround memory leak
davs2_decoder_close doesn't free those on the fly frames which
don't get output yet. It's a design bug, but easy to workaround.

Before the patch:
Direct leak of 1198606 byte(s) in 2 object(s) allocated from:
    #0 0x563af5e1e5f0 in malloc (ffmpeg+0x6675f0)
    #1 0x563af9765ef3 in davs2_malloc davs2/source/common/common.h:1240
    #2 0x563af9765ef3 in davs2_alloc_picture davs2/source/common/header.cc:815

Indirect leak of 3595818 byte(s) in 6 object(s) allocated from:
    #0 0x563af5e1e5f0 in malloc (ffmpeg+0x6675f0)
    #1 0x563af9765ef3 in davs2_malloc davs2/source/common/common.h:1240
    #2 0x563af9765ef3 in davs2_alloc_picture davs2/source/common/header.cc:815
