Subject: ocfs2: fix panic in failed foilio allocation
Date: Fri, 11 Apr 2025 11:31:24 -0500

commit 7e119cff9d0a ("ocfs2: convert w_pages to w_folios") and commit
9a5e08652dc4b ("ocfs2: use an array of folios instead of an array of
pages") save -ENOMEM in the folio array upon allocation failure and call
the folio array free code.

The folio array free code expects either valid folio pointers or NULL. 
Finding the -ENOMEM will result in a panic.  Fix by NULLing the error
folio entry.
