Fix stack buffer overflow in HUF_readCTable()
...
If `w ==0` on line 153, then `CTable[n].nbBits == tableLog + 1`.
Then `nbPerRank[CTable[n].nbBits]` and `valPerRank[CTable[n].nbBits]`
are stack buffer overflows.

Fix buffer overrun in ZSTD_loadDictEntropyStats()
...
The table log set by `FSE_readNCount()` was not checked in
`ZSTD_loadDictEntropyStats()`. This caused `FSE_buildCTable()`
to stack/heap overflow in a few places.
The benchmarks look good, there is no obvious compression performance regression:
