[ Upstream commit 4bcda1eaf184e308f07f9c61d3a535f9ce477ce8 ]
If no page could be allocated, an error pointer was used as format
string in pr_warn.
Rearrange the code to return early in case of OOM. Also add a check
for the return value of d_path.
Fixes: f8b92ba67c ("mount: Add mount warning for impending timestamp expiry")
