In dict_index_t::clear(), InnoDB frees all the page except root page.
root page leaf segment has reset and does reinitialize again.
t in fseg_create(), we do have the assumption that only
FIL_PAGE_TYPE_TRX_SYS or FIL_PAGE_TYPE_TRX_SYS page should
be re-created for non-full-crc32 format. This assumption is wrong
in case of rollback of bulk insert operation.
