powercap: intel_rapl: Use %pe to print error pointers symbolically

Replace PTR_ERR() and %ld with %pe and pass the original pointer directly
to pr_debug(). The %pe format specifier prints a symbolic error name
(e.g. -ENOMEM) when CONFIG_SYMBOLIC_ERRNAME is enabled, otherwise it falls
back gracefully and prints the raw integer value. This makes messages more
readable without any functional change.
