mm/zswap: use %pe to print error pointers

Browse Source 
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.
