MDEV-17898 FLUSH PRIVILEGES crashes server with segfault
merge_role_db_privileges() was remembering pointers into Dynamic_array
acl_dbs, and later was using them, while pushing more elements into the
array. But pushing can cause realloc, and it can invalidate all pointers.
Fix: remember and use indexes of elements, not pointers.
