Filter to preflight or hijack clearing a scheduled hook.

Returning a non-null value will short-circuit the normal unscheduling
process, causing the function to return the filtered value instead.

For plugins replacing wp-cron, return the number of events successfully
unscheduled (zero if no events were registered with the hook) or false
or a WP_Error if unscheduling one or more events fails.

$pre = apply_filters( 'pre_clear_scheduled_hook', null, $hook, $args, $wp_error );
