Make pr_xxx() call to use the %pe format specifier instead of %d. The %pe specifier prints a symbolic error string (e.g., -ENOMEM, -EINVAL) when given an error pointer created with ERR_PTR(err).
This change enhances the clarity and diagnostic value of the error message by showing a descriptive error name rather than a numeric error code.
Note, that some err are still printed by value, as those errors might come from libfdt and not regular errnos.
