[PATCH] libata: implement ata_dev_disable()
This patch implements ata_dev_disable() which prints a warning message
and takes @dev offline. Currently, this is done by explicitly
incrementing dev->class with case-by-case warning messages. Giving
user clear indication when libata gives up will be more important as
libata will be doing more retries.
