Does it help if you just remove the

	if (atomic_read(&page->count) > 2)
		goto out;

from shmem_writepage()?

It _shouldn't_ matter (because writepage() should only be called with
inactive pages anyway), but your problem certainly sounds like your
inactive dirty list is not able to write out shmfs pages.

Note that if you don't have swap, you're screwed anyway. You just don't
have anywhere to put the pages.
