WritableStream: minor bug fixes

WritableStream: minor bug fixes

* Constructing a WritableStream with a highWaterMark of NaN resulting in
  a TypeError. It should have been a RangeError. Fixed.
* Constructing a WritableStreamDefaultController should fail if the
  WritableStream already had a controller. It did not. Fixed.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

Are there any tests?

Yes. The tests in https://codereview.chromium.org/2500833002/
found both these bugs.

I think the bug fixes are logically separate from updating the
tests, that's why I put them in separate CLs.
