- InnoDB AHI tries to access the concurrent instant alter column,
leads to asan failure. Instant alter column should acquire the
clustered index search latch in exclusive mode before changing
the table cache definition.

- Removed the default parameter for the function
btr_search_drop_page_hash_index()

- Addressed the DWITH_INNODB_AHI=0 compilation failure
by passing two parameters from all callers of
btr_search_drop_page_hash_index()
