Fix for iPads running iOS 9 to no longer crash on pw generation.

Fix for iPads running iOS 9 to no longer crash on pw generation.

A new code path for autofill/password-generation views was added in https://codereview.chromium.org/1305433003 to support iPads running iOS 9 which no longer have a keyboard accessory. However, that change assumed that the view was an autofill view and crashed in the password generation case.  This CL fixes the assumption.
