Thank you for the contribution @FMLS
Using reflect check for nil isn't always right, as it's possible to have a nil value that implements the error interface,
https://play.golang.org/p/5T8S35zdGsH
To handle nil in this case, please follow the same logic used by Stringer to detect a nil panic (which uses recover, similar to the standard library).

We shouldn't panic if the `Error()` method of an `error` panics.
```
type T struct{ msg string }
func (t *T) Error() string { return t.msg }
// The following panics.
var n *T = nil
log.Info("panic", zap.Error(n))
```
