This optimizes firewire-sbp2's device probe for the case that the local node and the SBP-2 node were discovered at the same time. In this case, fw-core's bus management work and fw-sbp2's login and SCSI probe work are scheduled in parallel (in the globally shared workqueue and in fw-sbp2's workqueue, respectively). The bus reset from fw-core may then disturb and extremely delay the login and SCSI probe because the latter fails with several command timeouts and retries and has to be retried from scratch. We avoid this particular situation of sbp2_login() and fw_card_bm_work() running in parallel by delaying the first sbp2_login() a little bit. This is meant to be a short-term fix for https://bugzilla.redhat.com/show_bug.cgi?id=466679. In the long run, the SCSI probe, i.e. fw-sbp2's call of __scsi_add_device(), should be parallelized with sbp2_reconnect(). Problem reported and fix tested and confirmed by Alex Kanavin.
