Bartlomiej Zolnierkiewicz 303f1a76ae [libata] pata_efar: add locking for parallel scanning 
Add clearing of UDMA enable bit also for PIO modes and then add
extra locking for parallel scanning.

This is similar change as commit 60c3be3 for ata_piix host driver
and while pata_efar doesn't enable parallel scan yet the race could
probably also be triggered by requesting re-scanning of both ports
at the same time using SCSI sysfs interface.
