[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.
