3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

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

From: Hannes Reinecke <hare@suse.de>

commit b6c92b7e0af575e2b8b05bdf33633cf9e1661cbf upstream.

The .eh_abort_handler needs to return SUCCESS, FAILED, or
FAST_IO_FAIL. So fixup all callers to adhere to this requirement.
