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.


sql/mysql_priv.h:
  - removed 'grant_option' flag.
sql/sql_acl.cc:
  - removed 'grant_option' flag.
sql/sql_db.cc:
  - removed 'grant_option' flag.
sql/sql_insert.cc:
  - removed 'grant_option' flag.
sql/sql_parse.cc:
  - removed 'grant_option' flag.
  - removed unnecessary variables found_access, found
sql/sql_show.cc:
  - removed 'grant_option' flag.
sql/sql_update.cc:
  - removed 'grant_option' flag.
sql/sql_view.cc:
  - removed 'grant_option' flag.
