ata: libata-core: Do not try to set sleeping devices to standby
commit 4b085736e44dbbe69b5eea1a8a294f404678a1f4 upstream.
In ata ata_dev_power_set_standby(), check that the target device is not
sleeping. If it is, there is no need to do anything.
Fixes: aa3998dbeb ("ata: libata-scsi: Disable scsi device manage_system_start_stop")
