lib/alloc_tag: use %pe format specifier

The %pe format specifier is designed to print error pointers.  It prints a
symbolic error name (eg.  -EINVAL) and it makes the code simpler by
omitting PTR_ERR();

This patch fixes this cocci report:
lib/alloc_tag.c:776:63-70: WARNING: Consider using %pe to print PTR_ERR()
