libata: relocate and fix post-command processing
Some commands need post-processing after successful completion. This was done in ata_scsi_qc_complete() till now but this has the following problems. * Post-command processing gets executed when qc is completed from EH. Some qc's are retried from EH with zero err_mask and thus triggers unnecessary/incorrect post-command processing. * Command post processing doesn't belong to SAT layer. * Link-wide revalidation was scheduled where device revalidation suffices. This patch moves post-command processing to success completion path of ata_qc_complete() which is travelled iff the command is going to be completed without passing through EH and updates post-command processing such that device-specific action is used. While at it, restructure code a bit for readability. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
