mm/vmscan: use %pe to print error pointers
Use the %pe printk format specifier to report error pointers directly
instead of printing PTR_ERR() as a long value. This improves clarity,
produces more readable error messages.
This instance was flagged by the Coccinelle script
(misc/ptr_err_to_pe.cocci) as an opportunity to adopt %pe.
Found by: make coccicheck MODE=report M=mm/
No functional change intended
