cpufreq: Use %pe to print error pointers symbolically

Browse Source 
Replace PTR_ERR() and %ld with %pe and pass the original pointer directly
to pr_err() and pr_warn(). 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.
