Nick Terrell 4db751668f Fix buffer overrun in ZSTD_loadEntropy()
The table log set by `FSE_readNCount()` was not checked in
`ZSTD_loadEntropy()`.  This caused `FSE_buildDTable(dctx->MLTable, ...)`
to overwrite the beginning of `dctx->hufTable`.

The benchmarks look good, there is no obvious performance regression:
