    A fix for Bug#7209 "Client error with "Access Denied" on updates · f7d6fa6f

    when high concurrency": remove HASH::current_record and make it
    an external search parameter, so that it can not be the cause of a 
    race condition under high concurrent load.
    The bug was in a race condition in table_hash_search,
    when column_priv_hash.current_record was overwritten simultaneously
    by multiple threads, causing the search for a suitable grant record
    to fail.
    No test case as the bug is repeatable only under concurrent load.
