ceph: remove bogus checks and WARN_ONs from ceph_set_page_dirty
[ Upstream commit 22d41cdcd3cfd467a4af074165357fcbea1c37f5 ]
The checks for page->mapping are odd, as set_page_dirty is an
address_space operation, and I don't see where it would be called on a
non-pagecache page.
The warning about the page lock also seems bogus. The comment over
set_page_dirty() says that it can be called without the page lock in
some rare cases. I don't think we want to warn if that's the case.
