MDEV-22677 UPDATE crashes on partitioned HEAP table WITHOUT OVERLAPS

Browse Source 
`ha_heap::clone` was creating a handler by share's handlerton, which is
partition handlerton.

handler's handlerton should be used instead.

Here in particular, HEAP handlerton will be used and it will create ha_heap
handler.
