CVE-2025-22073

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

spufs: fix a leak on spufs_new_file() failure

It's called from spufs_fill_dir(), and caller of that will do
spufs_rmdir() in case of failure.  That does remove everything
we'd managed to create, but... the problem dentry is still
negative.  IOW, it needs to be explicitly dropped.
