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.
