hw/ide/core: Clear LBA and drive bits for EXECUTE DEVICE DIAGNOSTIC
Prior to this patch, cmd_exec_dev_diagnostic relied upon
ide_set_signature to clear the device register. While the
preservation of the drive bit by ide_set_signature is necessary for
the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands,
ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE
DEVICE DIAGNOSTIC.
This deviation was uncovered by the ATACT Device Testing Program
written by Hale Landis.
