WP_REST_Settings_Controller::sanitize_callback()
Custom sanitize callback used for all options to allow the use of 'null'.
By default, the schema of settings will throw an error if a value is set to null as it's not a valid value for something like "type => string". We provide a wrapper sanitizer to allow the use of null.

No Hooks.
Return
Mixed|WP_Error
