MDEV-30397: MariaDB crash due to DB_FAIL reported for a corrupted page
buf_read_page_low(): Map the buf_page_t::read_complete() return
value DB_FAIL to DB_PAGE_CORRUPTED. The purpose of the DB_FAIL
return value is to avoid error log noise when read-ahead brings
in an unused page that is typically filled with NUL bytes.
If a synchronous read is bringing in a corrupted page where the
page frame does not contain the expected tablespace identifier and
page number, that must be treated as an attempt to read a corrupted
page. The correct error code for this is DB_PAGE_CORRUPTED.
The error code DB_FAIL is not handled by row_mysql_handle_errors().
This was missed in commit 0b47c126e31cddda1e94588799599e138400bcf8
(MDEV-13542).
