Potential memory leak in IntelDeflater

[gspowley]

We need to free the memory allocated for huffman tables on this line of IntelDeflater.cc, unless the ISA-L code is doing that for us.

@pnvaidya can you please take a look at this on Monday?

[pnvaidya]

You are right, since we are allocating the tables in our code, we will have to clean it up, not ISAL…

if (level != 1) {
deflateEnd(lz_stream);
}
else
{
free(hufftables_custom);
free(lz_stream);
}

Let me add this change to existing pull request.
