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.
