Bug#24988 FLUSH PRIVILEGES causes brief unavailability

Browse Source 
- A race condition caused brief unavailablility when trying to acccess
  a table. 
- The variable 'grant_option' was removed to resolve the race condition and
  to simplify the design pattern. This flag was originally intended to optimize
  grant checks.
