excluded_if panic on nil tag parameter

[DarkReduX]

• I have looked at the documentation here first?
• I have looked at the examples provided that may showcase my question here?

Package version eg. v9, v10:

V10

Issue, Question or Enhancement:

tag excluded_if
app panics on nil field value in tag param

Code sample, to showcase or reproduce:

type Testr struct {
	W *int
	R *int `validate:"excluded_if=W nil,max=10"`
}

func TestN(t *testing.T) {
	v := validator.NewMapValidator()

	var (
		r = 0
		w = 10
	)

	err := v.Struct(Testr{
		W: &w,
		R: &r,
	})
	t.Fatalf("%s", err)

}

Output

panic: strconv.ParseInt: parsing "nil": invalid syntax [recovered]
panic: strconv.ParseInt: parsing "nil": invalid syntax
