CVE-2025-37950

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: fix panic in failed foilio allocation

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.
