fix: do not abort check on ignored fields

[22dm]

type Nested struct {
    NoTagA string
}

type Foo struct {
    Ignored Nested `json:"-"`
    NoTagB  string
}

Such a structure should report an error because NoTagB lacks the json tag. However, it currently does not, because the misplaced return instead of continue is made in the code, which skips the check of subsequent fields.

Good catch, I totally missed that 😅
