This is intended to workaround bug "665 Integer Divide Instruction May
Cause Unpredictable Behavior" on some early AMD CPUs, which causes a
div-by-zero in this codepath, such as reported in Mozilla bug #1293996.
Note that this isn't guaranteed to fix the bug, since a compiler is free
to reorder instructions that don't depend on each other. However, it
appears to fix the bug in Firefox, and a similar patch was applied to
libvpx also (see Chrome bug #599899).

Negative values don't make sense and too large values can cause
overflows. For AV_CODEC_ID_ADPCM_THP this leads to a too small extradata
buffer being allocated, causing out-of-bounds writes.
