Bug#41079 information_schema.schema_privileges is limited to 7680 records.

Browse Source 
The problem is that we cannot insert new record into memory table
when table size exceeds max memory table size.
The fix is to use schema_table_store_record() function which
converts memory table into MyISAM in case of table size exceeding.

Note:
There is no test case for this bug, the reason is that
1. The code  that was added already is checked(i.e. works) with existing tests
2. Correct work of schema_table_store_record() is checked with other test cases
   (information_schema tests)
So new code is fully covered with existing test cases.
