[SCSI] fix oops in scsi_release_buffers()
I found one other thing that needs to be fixed. The call to scsi_release_buffers in scsi_unprep_request causes an oops, because the sgtable has already been freed in scsi_io_completion. The following patch is needed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
