libata: factor out ata_eh_schedule_probe()
Factor out ata_eh_schedule_probe() from ata_eh_handle_dev_fail() and
ata_eh_recover(). This is to improve maintainability and make future
changes easier.
In the previous revision, ata_dev_enabled() test was accidentally
dropped while factoring out. This problem was spotted by Bartlomiej.
