Bug#12948130 UNNECESSARY X-LOCKING OF ADAPTIVE HASH INDEX (BTR_SEARCH_LATCH)
InnoDB acquires an x-latch on btr_search_latch for certain in-place updates
that do affect the adaptive hash index. These operations do not really need
to be protected by the btr_search_latch:
* updating DB_TRX_ID
* updating DB_ROLL_PTR
* updating PAGE_MAX_TRX_ID
* updating the delete-mark flag
