Jeff Layton 80b8fe47d0 generic: ensure that page is properly filled before write ...

We had a broken optimization in cephfs and netfs lib that could
cause part of a page to be improperly zeroed-out when writing to an
offset that was beyond the EOF but in an existing page.

Add a simple test that would have caught this.
