libata-eh set tf flags in NCQ EH result_tf

Fix mis-reporting of NCQ errors by ensuring that result_tf->flags
is properly initialized in libata-eh.  This allows ata_gen_ata_sense()
to report the failed block number correctly to SCSI after a media error
during NCQ.

This patch may also be a candidate for backporting to earlier kernels.
Without this fix, SCSI will fail I/O on the entire request rather
than just the bad sector.  That can be bad for a request that was
merged from many independent read reads from different tasks.
