Addition to fix for
BUG#25712 - insert delayed and check table run together report
crashed tables
Let MY_THREADSAFE have distinct value. Some functions call my_seek
passing MyFlags argument directly to it. This may cause unnecessary
locks, which may finally lead to a dead-lock (specifically see my_lock).

Also it doesn't affect my_pread/my_pwrite in any way. So the comment was
updated.
