ATA_FLAG_DISABLED is only used by drivers which don't use ->error_handler framework and is largely broken. Its only meaningful function is to make irq handlers skip processing if the flag is set, which is largely useless and even harmful as it makes those ports more likely to cause IRQ storms. Kill ATA_FLAG_DISABLED and makes the callers disable attached devices instead. ata_port_probe() and ata_port_disable() which manipulate the flag are also killed. This simplifies condition check in IRQ handlers. While updating IRQ handlers, remove ap NULL check as libata guarantees consecutive port allocation (unoccupied ports are initialized with dummies) and long-obsolete ATA_QCFLAG_ACTIVE check (checked by ata_qc_from_tag()).
