commit 908344cdda80 ("tipc: fix bug in multicast congestion handling") introduced two bugs with the bclink wakeup function. This commit fixes the missing spinlock init for the waiting_sks list. We also eliminate the race condition between the waiting_sks length check/dequeue operations in tipc_bclink_wakeup_users by simply removing the redundant length check.
