Damien George fa42487e45 extmod/moddeflate: Keep DeflateIO state consistent on window alloc fail. ...

Allocation of a large compression window may fail, and in that case keep
the `DeflateIO` state consistent so its other methods (such as `close()`)
still work.  Consistency is kept by only updating the `self->write` member
if the window allocation succeeds.

Thanks to @jimmo for finding the bug.
