Issues with RHFInput and validation

[piehouserat]

Describe the bug
When using a controlled component such as Material UI's radio group along with validation rules, validation errors are not cleared when the component is made valid

To Reproduce
Steps to reproduce the behavior:

1. Go to https://codesandbox.io/s/react-hook-form-rhfinput-vh5qc
2. Click on the submit button straight away (notice the validation message on the form)
3. Select one of the radio button options in order to fix the validation error
4. Validation error message is still displayed until clicking the submit button again

Expected behavior
Validation errors should disappear when the component is made valid using the default form mode of 'onChange'

you can add mode="onChange" to trigger validation onChange.
