ata: libata-core: Do not try to set sleeping devices to standby

Browse source 
commit 4b085736e4 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")
