#7074: Do not use av_free() to free avcodec_alloc_context3() return value

Details: In avcodec_dct_init(), the return value of
avcodec_alloc_context3() (called at line 90) is freed with av_free() (at
line 127). I think the expected paired function is avcodec_free_context().
For your convenience, I paste related bugs as follows:
{{{#!c
88 int avcodec_dct_init(AVDCT *dsp)
89 {
90 AVCodecContext *avctx = avcodec_alloc_context3(NULL);
91
92 if (!avctx)
93 return AVERROR(ENOMEM);
94
95 avctx->idct_algo = dsp->idct_algo;
96 avctx->dct_algo = dsp->dct_algo;
97 avctx->bits_per_raw_sample = dsp->bits_per_sample;
...
125
126 avcodec_close(avctx);
127 av_free(avctx);
128
129 return 0;
130 }
}}}
Thanks!
