Subject: [ 04/46] libata: ahci: Fix lack of command retry after a success error handler.

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bian Yu <bianyu@...acom.com>

commit 1eaca39a84170b369fe61fb1da3c1e8606859e99 upstream.

It should be a mistake introduced by commit 8d899e70c1b3afff.

qc->flags can't be set AC_ERR_*
