[SCSI] ipr: Proper return codes for eh_dev_reset for SATA devices
Currently ipr always returns success from eh_dev_reset when called for a SATA device. If ata_do_eh is unable to recover for some reason, this can result in commands that are still outstanding when ata_do_eh returns. Change ipr to verify no commands are outstanding before returning success. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
