It looks like we can call this in Close's callback task and get rid of another
PostTaskAndReply in pepper_plugin_delegate_impl?

Done.
The tricky thing here is that in the callback we have no direct access to
plugin_delegate anymore. The new patch set encapsulate it in a callback object.

     file_ = base::kInvalidPlatformFileValue;
     quota_file_io_.reset();
   }
