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.

now if only I had a way for the SAT to issue CHECK POWER MODE (used in
TEST UNIT READY translation), and inspect qc->err_mask before EH gets
its hands on it... :)
