Re: [PATCH scsi-misc-2.6 05/07] scsi: move scsi_init_cmd_errh() from request_fn to prep_fn.

From: Tejun Heo

05_scsi_requeue_move_init_cmd_errh.patch

As now all non-reprepped requeue goes through
scsi_retry_command() which clears sense buffer, there's no
need to call scsi_init_cmd_errh() in scsi_request_fn(). Move
scsi_init_cmd_errh() to scsi_prep_fn().
