    [SCSI] aacraid: fix potential panic in thread stop
    Got a panic in the threading code on an older kernel when the Adapter
    failed to load properly and driver shut down apparently before any
    threading had started, can not dupe. Expect that this may be relevant in
    the latest kernel, but not sure. This patch does no harm, and should
    alleviate the possibility of this panic.
