Similar to how AHCI handles NCQ errors in ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort(), add an NCQ error handler for LLDDs to call to initiate a link abort. This will mark all outstanding QCs as failed and kick-off EH. Note: A "force reset" argument is added for drivers which require the ATA error handling to always reset the device. A driver may require this feature for when SATA device per-SCSI cmnd resources are only released during reset for ATA EH. As such, we need an option to force reset to be done, regardless of what any EH autopsy decides. The SATA device FIS fields are set to indicate a device error from ata_eh_analyze_tf().
