libata: fix incorrect link online check during probe
While trying to work around spurious detection retries for non-existent devices on slave links, commit 816ab897 incorrectly added link offline check logic before ata_eh_thaw() was called. This means that if an occupied link goes down briefly at the time that offline check was performed, device class will be cleared to ATA_DEV_NONE and libata wouldn't retry thus failing detection of the device. The offline check should be done after the port is thawed together with online check so that such link glitches can be detected by the interrupt handler and handled properly.
