[PATCH] libata-eh-fw: update ata_exec_internal() for new EH

Update ata_exec_internal() such that it uses new EH framework.
->post_internal_cmd() is always invoked regardless of completion
status.  Also, when ata_exec_internal() detects a timeout condition
and new EH is in place, it freezes the port as timeout for normal
commands would do.

Note that ata_port_flush_task() is called regardless of
wait_for_completion status.  This is necessary as exceptions unrelated
to the qc can abort the qc, in which case PIO task could still be
running after the wait for completion returns.
