Hi James,

the FAILFAST flag is currently not honored in scsi_request_fn().
So if scsi_dispatch_cmd() returns an error or the queue is not
ready, the request will always be requeued regardless of the
FAILFAST setting.
This can result in a delayed fallback for multipathing, as
these requests will only be catched once the timeout expires.

This patch avoids requeuing if the FAILFAST flag is set, and
terminates the request immediately.

Comments et al welcome.

Cheers,

Hannes
