zlib crashes when given windowBits: 8 #14847

On the above versions of Node, this program crashes:

var zlib = require('zlib');
zlib.createDeflateRaw({windowBits: 8});

I believe this coincides with bumping zlib from 1.2.8 to 1.2.11, but I'm not 100% sure. I'm not sure if 8 is no longer a legal value, but zlib.Z_MIN_WINDOWBITS equals 8 on affected platforms.
