This is a partial backport of semver-patch bits of
9e4660b.

This commit fixes the Node process crashing when constructors of classes
of the zlib module are given invalid options.

* Throw an Error when the zlib library rejects the value of windowBits,
  instead of crashing with an assertion.

* Treat windowBits and memLevel options consistently with other ones and
  don't crash when non-numeric values are given.

Unset `mode_` when initializing the zlib stream failed, so that
we don’t try to call the zlib end functions (`deflateEnd()` etc.)
when cleaning up in `ZCtx::Close()`.
