libata: sanitize ata_tf_read_block()
Return U64_MAX if ata_tf_read_block() could not decode the LBA address, and do not set the information sense descriptor in ata_gen_ata_sense() in these cases. tj: s/(u64)-1/U64_MAX/ Signed-off-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Tejun Heo <tj@kernel.org>
