avcodec/qdm2, vorbisdec: Use compile-time const max_depth in get_vlc2
It makes no sense to try to be exact with max depth
in get_vlc2(): It will mean that the compiler emits code
for all three stages of parsing and runtime checks for
whether max_depth is big enough to parse the next stage
when a not yet complete code has been encountered.
