avcodec/g723_1enc: Make min_err 64bit 
This is intending to fix the case described in https://lists.ffmpeg.org/archives/list/ffmpeg-devel@ffmpeg.org/thread/AAZ7GJPPUJI5SCVTDGJ6QL7UUEP56WOM/
Where FCBParam optim is used uninitialized

a min_err of 1<<30, allows the struct to be never initilialized as all
err (which is int32_t) can be larger than min_err. By increasing min_err
above the int32_t range this is no longer possible

Untested, as i do not have the testcase
