[PATCH 3.17 15/73] scsi: correct return values for .eh_abort_handler implementations

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

3.17-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.
