libata: give devices one last chance even if recovery failed with -EINVAL
After certain errors, some devices report complete garbage on
IDENTIFY. This can cause ata_dev_read_id() to fail with -EINVAL
resulting in immediate disabling of the device. Give the device one
last chance after -EINVAL to allow recovery from such situations. As
-EINVAL is triggered very rarely, this shouldn't cause any noticeable
affect on more common error paths.
