libata-eh.c: Introduce new ata port flag for controller which lockup on read log page
Some controller lockup on a ata_read_log_page.
Add new ata port flag ATA_FLAG_NO_LOG_PAGE which can used
to blacklist a controller.
If this flag is set, any attempt to read a log page returns an error
without actually issuing the command.
