[PATCH] libata: move err_mask to ata_queued_cmd

Browse Source 
- remove err_mask from the parameter list of the complete functions
  - move err_mask to ata_queued_cmd
  - initialize qc->err_mask when needed
  - for each function call to ata_qc_complete(), replace the err_mask parameter with qc->err_mask.
