libata: kill dead code paths in reset path
Some code paths which had been made obsolete by recent reset
simplification were still around. Kill them.
* ata_eh_reset() checked for ATA_DEV_UNKNOWN to determine
classification failure. This is no longer applicable.
* ata_do_reset() should convert ATA_DEV_UNKNOWN to ATA_DEV_NONE
regardless of reset result (e.g. -EAGAIN).
* LLDs don't need to convert ATA_DEV_UNKNOWN to ATA_DEV_NONE.
